The Old Poisoned Banana Trick
From The Age (Australia):
The teacher could not believe what he overheard. The "visiting" imam was launching into a tirade against the Jews and Americans that bordered on the ludicrous.I don't know about "bordered on the ludicrous". I'd say the imam has passed through ludicrous on the way to delusional.
But then came the clincher, he recalled. "The imam told the students that the Jews were putting poison in the bananas and they should not eat them."
