Sylvain Estadieu to swim butterfly across the English Channel

Sylvain Estadieu aka The Flying Frenchman, who soloed the English Channel in 2009 and before that swam a notorious Indidual Medley of Sandycove Island, will this September attempt to do the English Channel in butterfly only. Last week he managed a personal best 8-hour session of approximately 21.5K of butterfly. Why? He has some hilarious answers on his blog:

Do I do it to pick up chicks in bars?
NO! Go and ask the Viking Princess what she thinks about this!
Do I do it for money?
Hahahahahahahahahahahahahahahahaha!
