Ba-zin-ga!!!!!!
Sheldon mimics Bernadette and Penny's conversation by asking Howard about his shoes.
Bazinga is a word used by Sheldon Cooper to accompany his jokes and pranks. Sheldon's ability to surprise people with jokes is rooted by his apparent inability to recognize sarcasm and his inability to recognize when he is being too harsh in certain social situations. This leads to a natural assumption that he will always be blunt or harsh, but because of this assumption, he is able to easily interject pranks or jokes into conversations.
The word "Bazinga" was first used in the season 2 season finale, "The Monopolar Expedition."
Notable episodes with Bazinga! include S05E07 The Good Guy Fluctuation (Leonard, who had just broken up with Priya via laptop camera/microphone, then gets frightened by Sheldon rising from his hiding spot under the cushions "Bazinga, punk. Now we're even.") and S03E14 The Einstein Approximation (Leonard unsuccessfully tries to pull Sheldon out of a ball pit, Sheldon keeps bobbing his head up to taunt Leonard with "Bazinga!" before hiding back down in the ball pit).
Jim Parsons has been quoted as crediting former The Big Bang Theory writer Stephen Engel as the one who came up with the word Bazinga for Sheldon's catchphrase. Furthermore Bazinga implies swag.

Sheldon: There’s just no pleasing you, is there, Leonard? You weren’t happy with my previous approach to dealing with her, so I decided to employ operant conditioning techniques, building on the work of Thorndike and B.F. Skinner. By this time next week, I believe I can have her jumping out of a pool, balancing a beach ball on her nose.
Leonard: No, this has to stop now.
Sheldon: I’m not suggesting we really make her jump out of a pool. I thought the “Bazinga” was implied.

Priya: Well, it’s not a competition.
Leonard: Oh yeah, it is, and you won. I, I, I’m, I’m sorry, I have to go (closes lid on laptop as Leonard had been communicating with Priya through the camera/microphone on his laptop). I don’t believe this.

S05E22 "The Stag Convergence"
Sheldon: (saying some words about Howard at the bachelor party) As is the tradition, I have prepared a series of disrespectful jokes which generate humour at Howard’s expense. Prepare to have your ribs tickled. Howard, I always thought you’d be the last one of us to ever get married, because you are so short and unappealing. Am I right? Let’s see here. Oh, seriously though, Howard, you’re actually one of the most intelligent people I know. And that’s a zinger, because you’re not. I’ve always thought that you’d make someone a fine husband someday. Assuming you’d be able to get the parts, and develop the engineering skills to assemble them, which I don’t see as likely. Hacha! Okay, let me see here. Okay, kidding aside, Howard, you are a good friend. And I wish you nothing but happiness. Bazinga, I don’t!
Leonard: Sheldon…
Sheldon: Doubleazinga! I do! Good luck following that.
Raj: (revealing Howard's sexual history) I think back to all the good times we had, like, uh, when we went camping and spent that night telling each other all our secrets. I told him I’m addicted to pedicures and he told me he lost his virginity to his cousin.
Howard: She was my second cousin.
Sheldon: And the first woman you ever disappointed sexually. Ba-da-bazinga!
