Sad, disrespectful and disgusting.  I don't have much use for the French at times, and this is not the only instant.   This is a race that their country is hosting, for athletes the world 'round, and they jeer the leader of this race??   Hopefully, this is just a few jerks, but I heard he was getting these displays semi-frequently.  Maybe it will anger him enough to really burn and win it in style. 

Go on Lance...show 'em how it's done!
