I hate to quote Family Guy, but this is one of my favorite lines from when the family visits Ground Zero:

Peter: Ground Zero. So this is where the first guy got AIDS.
Brian: No, Peter, this is the site of the 9/11 terrorist attacks!
Peter: Oh, so Saddam Hussein did this?
Brian: No.
Peter: The Iraqi army?
Brian: No.
Peter: Some guys from Iraq?
Brian: No.
Peter: That one lady who visited Iraq that one time?
Brian: No, Peter, Iraq had nothing to do with this. It was a bunch of Saudi Arabians, Lebanese, and Egyptians financed by a Saudi Arabian guy living in Afghanistan and sheltered by Pakistanis.
Peter: So…you’re saying we need to invade Iran?
