I got these out of a "gross jokes" book at school. I love it!
What is red and green and goes 120 mph? A frog in a blender.
What's another name for a snail? A booger with a crash helmet!
Why don't elephants pick their noses? Because what can you do with a 20 pound booger?
What has two grey legs and two brown legs? An elephant with diarrhea.
What do you get when you cross an elephant with a box of laxatives? Out of the way.
What's yellow and smells like bananas? Monkey vomit.
Hope you had a good laugh, I know I sure did when I was first reading them. My favorite is definitely the snail one!
