“Bazinga!” (Sheldon, Big Bang Theory)

Sheldon Cooper is not exactly a natural prankster, which is precisely why “Bazinga!” works. The word became his personal exclamation point after a joke or attempted deception, delivered with the confidence of someone who believes the social interaction has now been successfully completed. It’s loud, unmistakable and inseparable from Sheldon — all major weapons in a catchphrase bracket. It also has haters, which might make its matchups even better. Does “Bazinga!” have the staying power to beat older staples like “Did I do that?” or “Whatchu talkin’ ’bout, Willis?” There’s no neutral corner here. Sheldon people are going to defend it. Everyone else gets a vote.
