I just got level 7 with Ivern

Someone made a post making this exact same pun yesterday. https://boards.na.leagueoflegends.com/en/c/memes/r1z3UuLH-what-does-ivern-say-to-the-shopkeeper-after-a-long-day-of-brutally-murdering-champions?comment=0000

I'm sure it has been done numerous times before, but that's a bit close.

You could always try for a Riven-ge pun. It's sorta similar to an Ivern pun, but misspelled.
