What's the best prank you ever pulled?

my brother was about to leave for Kelsy's (where he works) and i decided to give him a "hug" b4 he left to say goodbye. well luckily he didn't notice that i stuck a big peice of paper of his back that said "kick me" (of course). and he still had it on his back when he got to work! no one kicked him but all of the employies were laughing at him and finally someone told him but it was rlly funny!
