@bart: i once popped my jaw in a really weird way, by pushing it far to one side. the next day i was eating a big piece of sushi and it kinda locked, like it was really painful and i couldn't open it very far. luckily that went away and i've never popped my jaw so extremely since. oh my g*d i hate it when it locks… but bart, u have given me the idea for a new thread!!
