First penta was this summer, on Annie (MID). Things weren't going so hot, I was going back to lane after dying in a teamfight. I notice our Nunu is hanging around baron, the enemy is starting it. My 3 other teammates are also heading toward baron, so I decide to go through the jungle.To my delight, Nunu steals it.
My team retreats; top and adc die. Enemy chases us into our jungle. Around blue buff, I tibbersbomb and instagib by surprise 2 of them. I am not sure how the third one died, but I remember dueling and melting Udyr after that. At that point, Lulu, my only teammate left alive, died to shield/ult me against the fed Lissandra. And then it was gg, pentakill, laughing and dancing around my keyboard.
We lost the game after that (well loss forgiven, but we where super behind anyways).
I guess the funniest would be my only other penta. I am Vel'koz support, and not doing very hot again. Enemy team didn't have an extraordinary laning, but they grouped earlier and took objectives.
2 of my dudes are dead, one is in spawn, it's just me and jungle Zac midlane. The five enemies are there, grouped up. Zac goes in full-on yolo style with no warnings whatsoever, and hits all of them somehow. I ult too, drop the enemy pretty low. As Zac dies (no passive), I wonder if I should go in for a good half-second before deciding of fucking course I should go in. I flash in, use everything, quadra.
Morgana is running away and escapes my cc with her stupid blackshield. I chase her till that one little bush near drag when she goes toward me and let me kill her. All the 8 other players where telling her to give Penta.
My team rallied with raised morale afterwards and we won the game with a Yi quadra.
