Just for information's sake, a belly burp is when you blow a raspberry on someone's belly/stomach/tummy.

1) Have you ever belly burped someone?
2) Have you ever been belly burped?
3) Does it tickle when you're belly burped?
4) One bullet. One gun. John Kerry, George Bush, Tony Blair. What would you do?

1) Yes.
2) Yes (but a long time ago).
3) It used to, but I haven't been belly burped for a long time, so I don't know.
4) Line up Bush and Blair and shoot them in the head.
