Really Funny Clean Jokes and Humor

I know this great april fools day prank so here's what it is, make pancakes for your family for breakfast, and put a string of yarn or something in only one of them and give it to whoever you want to and when they try to cut it they can't and if they eat without cutting it they won't be able to bite it and if they can bite it they get a big string in their mouth I do it every year on somebody new and don't even get in trouble for it they love it!!
