A blonde, brunette and redhead all decide to participate in the swimming of the English channel.
They all decided to do the same stroke as it would be fair and they should all finish at the same time. Not wanting to lose energy quickly, they chose breast stroke.
They all started and a few hours later, the brunette arrives on land, tired.
The next one to complete it, was the redhead, a couple of hours behind the brunette.
Lastly, 6 hours after the brunette had arrived, the blonde clambers on shore, absolutely exhausted.
When the TV crew arrived, they asked her why she took so long, she replied: "Not to be a sore loser or anything but I'm pretty sure I saw the other two using their arms."
