What do you get when you cut an onion?
Onion jizz.
Hey, dummy! "Jizz" sounds like "juice". When you cut an onion, juice comes out. It's funny because people don't expect to hear the word "jizz" when talking about onions. That's the joke, ya cotton-headed ninny muggins! And just so you know, you're probably not getting enough fiber in your diet. SAD!
