I wish i had a cam to show you but my dad wont let me use it, so im gonna tell you word from word. Take a propane,gas tank, or a oxygen tank on the lift with you on No Mercy 3 The Sewers. Wait till the lever goes half way up and throw it at the floor by anyone of your partners. They should fall through. Go back down and look at them and they should be stuck and cant get out. Funny prank, huh? Please o please leave comment, i wanna hear what you people think about me.
