Ratchet and Clank: Size Matters Glitches

Get stuck in Clank
If you go in Clank and head to the room with eight doors (6 of which enemies come through), kill people until a Shock Trooper and an average technomite or two come toward you. Go against the pillar in the center and activate the shield thingy. They will all push against you. Run into the pillar and you should get stuck inside of it. You cannot attack the other people, and you cannot escape. (Caution: Very hard to do.)
