A blonde, brunette and redhead all decided to see who would swim the English channel the fastest. To be fair, they agreed to use the same stroke - breast stroke.
So they lined up and jumped into the water at the same time. A few hours later, the brunette arrived on the other side, tired. The redhead arrived a couple of hours after.
After six more hours, the blonde finally came ashore, absolutely exhausted. When the TV crew covering the event asked her why she took so long, she complained, "Not to be a sore loser or anything, but I think the other two used their arms."
