This one is from Geoff.
How about shaggy dog stories that include a REALLY bad pun? Here's one to start us off:

Atilla the Hun was among history's meanest men. He is reputed to have killed the first person he saw upon awakening, just out of sheer meanness. Needless to say, his attendants were thinning out rapidly, so they took council how to awaken Atilla in safety.

Upon pillaging a town, they discovered the town drunk in a wine vat unharmed. They thought that he might be a person whom they could use to awaken the boss - at least once. They told him that they would supply him with the finest wine they had in exchange for his awakening Atilla each day.

The next day the drunk staggered into Atilla's tent, shook him, and WHACK! out the drunk flew, slamming against a wagon, as Atilla bellowed his usual morning curses. The drunk staggered to his feet, unscathed by the blow.

The drunk withstood day after day, year after year of this ordeal, and became famous throughout the world as the
Souse of the Rising Hun.
