(This joke was published in one of Penn&Tellers books)First Im gonna teach u a really funny practical joke to doif your ever on a plane or long bus ride. When u ready to do joke start yawning like u tired and warn theperson next to that u sleep with your eyes open and if the stuartess comes to tell her u sleeping( if a bus just warn them and tell them u doing it cause it might look strange). Then pretend like u trying to go to sleep, but with your eyes OPEN. Then pretend like u asleep. U can start snoring and stuff. And its HALARIOUS if u tilt your head to the side and look them right in the eye. Mac King ( a famous magician) does this all the time and is a master at it and NEVER laughs. It will take some practice not to laugh, but if u pull it off its HALARIOUS!
Now for a scam! If u r at an airport and u wish to steal someones bag youll need a partner. You or your partner(for this example I'll say you) will line up in the metal detector line and go throgh. Then your prd.( who will have some metal things on him) will get in the line infront of the infront of the person u want to steal from. By the time the victem is in the metal detector line they would have already put they're bags in the x-ray machine and it should already be at the other end. Then your pard will go through the detector and it will go off and he will make a scene and he will take the thing out slowly, or whatever he has to do to stall the guy behind him from goingthrough and getting his bag. While u take his bag. Thats a good scam a lot of "grifters" use.
