The Big Bang Theory Bazinga Lucite Keychain displays the catchphrase BAZINGA! from the hit CBS television series The Big Bang Theory. On BOTH sides. So it's not like you're admiring your key chain...the bold red color of its insert...the even bolder BAZINGA!...and then you flip it over and there's nothing...nothing but maybe the white back of the red insert. It's not like that at all, because when you turn your Big Bang Theory Bazinga Lucite Keychain over, there it is again! You haven't been BAZINGA'd. The Bazinga is yours, my friend. All yours!
