We knew the events of The Big Bang Theory Season 8 Episode 10 would come someday, didn't we?
We know that Sheldon - with a girlfriend and a full-time job and a different life than he had a few years ago - simply wouldn't be able to continue Fun with Flags much longer, right?
Still, it hurts.
Sheldon Cooper Presents Fun With Flags at least went out with a bang: LeVar Burton showed up again. Amy dressed as a kangaroo. Kripke played Flag or Not a Flag. And Sheldon made like Betsy Ross.
He also grew emotional toward the show's end and taught us yet another use for a white flag.
