Really Funny Clean Jokes and Humor

This joke is mild but you can pull it any day of the year, what you do is get some fake blood (I use red cherry juice =D) and what you do is put the fake blood on one of your thumbs and go up to the person you are pranking and tell them you need help with your cut it is so funny to watch them try to help you when you just then suck the "blood" off and they look at you in discust XD
