Along the same line as putting water in someone's stick... You can put sand or small ball bearings into skate tuuks. Just pull out the cap in the heel under the footbed. It will make the skates weigh a ton. The bearings (or bbs) will probably be easier to get out.
anybody see the video going around the net of the shower prank? As the guy is rinsing shampoo out of his hair you just pour more back on top of his head and the suds keep flowing. I thought it was pretty funny. The guy just cant get the shampoo out of his hair and starts getting pissed.
i havent read through yet but the impossible situp is a great trick, or waiting until everyone is on the ice and tossing all their clothes into a garbage bag and only leaving panties and diapers for them to wear.
squirting dudes in the shower with dish soap and then turning the cold water off (usually in teh ceiling right by the shower) is great.
perfuming jerseys is funny
take a box cutter and slice right down the middle of everyones laces and then have a box of pink ones ($60ish) for them to use.
i played on a team one year where the year before some dude threw 2 live chickens into the dressing room, i didnt see it but it was supposedly hilarious.
at an old kids hockey camp i went to we took out the jock out of the goalies jockstrap, he didn't even notice until it was just about time to go on the ice. i felt bad and decided to give him the jock back, he was freaking horrified.
