What is Leonard catch phrase?

Leonard from "The Big Bang Theory" doesn't have a specific catchphrase like some other characters. However, he's known for saying "Bazinga!" which, while not a catchphrase in the traditional sense, is strongly associated with his character. He often uses it as a playful response after making a joke or tricking someone.

While "Bazinga!" isn't his only memorable line, it's the one that sticks out most and has become synonymous with Leonard himself.
