In first appearance he won the game by cheating, more like faking his granny's death to gain sympathy. But it didn't have much impact, fine.

But in season three episode 19 he literally breaks out a couple just to win the game! Sheldon wouldn't do that anytime. I was as angry as Sheldon because I loved them as couple

I would love to see these bloopers.

Season 1 Sheldon was more humorous and even though he didn't know sarcasm he always nailed it😂....This scene was what made me watch the show
