Two blond adventurers were on holiday, and went to see Niagara Falls.
After a few drinks one night, one bet the other $500 he couldn’t carry him across the falls on a tightrope.
After a very scary trip, his friend managed to stagger safely across, and the wager was duly paid.
“That was close,” said the loser. “When you wobbled, halfway across, I was sure I’d won.”
