i have 2 shyvanna dragon smite baron get double kill not very well executed and shaco q over wall smite flash and i escape in less then 1 second that was well executed the shyvanna one was choppy and i could of escaped so what is yours
this post would be better if riot got with the times and added a replay/DVR. explaining in text doesnt really make an epic moment feel epic.
even the 30 second "xbox record that" is better then nothing
DId noone else notice that OP had flash on Shaco?
Story #1: Our team was winning super hard, we had no vision on the Baron, but we saw the enemy team walked in. I walked up behind it as Caitlyn and Q'd into the pit thinking I could get lucky and finish someone who got low tanking it.
"You have slain the Baron Nashor."
The enemy team practically broke down in tears.
Story #2: It was a close match, we were a bit behind though in turrets and kills. We had vision on the Baron, so I walked up behind it as Sivir and waited for it to get low. With a wing and a prayer, I Q'd over the wall and with a little luck and some bad enemy smite-skills, the Baron buff was ours. My team finally caught up and a teamfight ensued. One by one, they dropped as they continued to fall back more and more, but we continued to press all the way to the nexus turrets. Where the fight finally concluded with this:
"Pentakill!"
Their nexus was only seconds behind.
My most recent was playing a Morg and the enemy team was being pretty cocky about getting Baron, starting it fairly low and just standing in the pit. They didn't see (or didn't care) that I warded because our jungler was dead. I managed to toss a binding over the wall to steal it and killed the jungler with my soil as he was actually that low (he was standing at the back of the pit for some reason), flashed over and got a double kill (triple altogether) with my ult as the adc and top were so low.
Not the most flashy play and more bad on them than good on me....but I'll be damned if it didn't make me feel good.
Fiddles 1v5 Baron/Ace. GG.
AD thresh 1v5 quadra only lost 50% of my hp and stole baron without ever attacking it 
I was Rammus, just rollin along, then notice the enemy doing Baron. I was like, "Hey guys!", smited it, and proceeded to run for my life.
My bro stole baron with a Varus Q once. In the end screen, one of the enemies said "I just died a little inside."
+ =
(OP)
Orianna shockwave from behind the wall.
Only had one Baron steal a long time ago
Team was a little behind, but the enemy decided 'We're super far ahead, we're just gonna go Baron and ignore the fact everyone's up.' I suspect they're doing it, but our wards were cleared so I decide, playing a tank Amumu, to go take a little waddle up and check it visually. See them there. Baron is low. Jungler smites it the instant they see me to try to rush Baron before my team shows up.
Bandage Toss onto one of them and hit Tantrum as Baron gets dangerously low.
has slain Baron Nashor!
Hit Curse of the Sad Mummy on all five of them and waddle off back down the river before they realize that my team isn't anywhere near me and is in fact kicking in the door on bot lane.
If we count Ascension, then I once stole the Ascension buff from the enemy team twice in one game by simply walking up to it with Garen, by myself, and spinning in the middle of all five of them.
I once was playing Diana, and my team thought there was no way I could get it ( I wasn't the jungler ) so I simply walked up to the enemy team getting baron flashed in used my W, Zhonya'ed and and got the baron.
Once I stole Baron with one of the last ticks of my Tormented Soil as support Morgana. (My teammates freaked out)
My whole team took teleport and smite. Our support warded the baron and when they went for it we waited until it was low and all teleported/smited then aced them, taking a clean win. 
Losing a game while defending base and no one was in out base. I'm playing adc 
. Screw it I say irl and ult at baron. You can guess what happened next.
My team wasn't doing to well and i was the only one that did good in lane and i was playing yasuo
the enemy team couldn't kill me unless i got stun locked but my team stood no chance against the other team so if i went back to buy items my team would lose the team fights until i got back from buying items
so the enemy team is doing baron and then i flashed over the wall and steal the baron with an unstacked yasuo E then dashed to the enemy adc killed them kited the enemy out of the baron pit and got the triple with my teams adc stealing the double kill i needed for the penta
My best Baron steal?
It's self explanatory
I stole baron with lucian ulti from the back then dash into the pit and pentakill with rammus. And one with Gnar boomerang (dat was the funniest).
I don't think I've actually ever successfully stolen a baron before. Lol.
The closest I've been is when all five of them were low, and I jumped into the pit as Jax. I failed my smite miserably but I managed to get a quad before dying to space-aids.
lux ult. no vision of baron.
Long before the preseason 5 2015 preseason changes...
Just blindly flash + smite the baron as jungle 
, no one calculated when was it gonna die and I didn't even look at the Baron HP bar. Then died.
Malz Q over wall with no vision of baron, wasnt even sure if they were doing it haha
All 5 of the enemy team walks through the river from midlane, derp, so I go to the other side of the wall, bcuz i have warded it, then wait till at 1400 hp, smite, killed it
Nautilus flash smite, we still lost but it felt good as fuck.
I was playing Xerath support and the enemy said they were doing baron so i ulted and stole it blindly
As a support, either as Leona, or Nami i cant remember! and using my Ult to steal it!
Their entire team was at baron, I'm 
. With flash on cooldown, I walk to the bush, and I know they saw me but they don't attack me. I step out of the bush and walk up to baron, they still don't attack me. I autoattack baron once and get Baron for my team, then they shoot me. 
yomuu's lucian ult from behind the pit
Well.... uhhhhhhh..... 
flash over the wall and smite?
Played Vel'koz support, we were way behind, I ulted Barron ftw. I got killed for it, but we won that is what matters.
Wasn't baron, but it was the ascension buff back when that mode was still around. But same idea.
auto attack.
