A blonde, a redhead, and a brunette all enter the International Breast Stroke Swim across the English Channel.
After about 8 hours, the brunette makes it across, followed shortly by the redhead. No sign of the blonde.
After 12 hours they decide they’d better go look for her when she pretty much washes up on shore.
They rush over to her and wrap her in warm blankets and give her a hot drink.
After a few minutes, she is breathing easier and says, “I don’t like to tattle, but I think those other ladies were using their arms!”
