Those that might be captives of their own self importance tend to be impressed by themselves and their own surroundings be they Squaw, Jackson, Baker whatever. Once you drive up the Cham Valley, that self absorption tends to diminish a bit. Hence, those that have been to Chamonix or that understand it, don't joke about it too much. Rather.......they tend to respect the reference.
Those that would tend to make the Cham reference a joking matter are deserving of a street corner and a clown suit.
Cham FOU!: (crazy)
