This reminds me of a trick I like to do...(and for once I'm not talking about poyeboy's girlfriend)
I put 3 plates on the bar while the gym is packed, then unrack and slowly lower it to my chest...then pretend like I can't get it up and start screaming "HELP ME FOR THE LOVE OF GOD I CAN HEAR MY STERNUM CRACKING" and when like 6 people rush over to help me I thrust the weight up and scream "AHAAHAH!!! PSYCH!!! JUST FUCKING AROUND ASSHOLES!!!".
Then I go get a drink.
