What's that on your uniform? A pledge pin?? No? No. It's our Big Bang Theory Bazinga Button! This Bazinga button measures about 1.25" and has a little pin and clasp on the back so you can...use it for wherever your outfit is lacking a whimsical button, which is just about everywhere, most likely! Given the hit TV show's use of the word, you might wanna conceal it under your lapel, until you pull off that first prank...then you can unveil it and give your rival his (or her) comeuppance without uttering a word. Let the Big Bang Theory button say it for you...BAZINGA!
