the british version was funny. seems like they improvised a bit more on that, meaning, the american version seems partly scripted/rehearsed. weird since a lot of those guys were on the british version quite regularly.
simmons on letterman was classic. what i liked about simmons was his ambiquity, which, at least on this video, he has lost, as he is blatantly showing homosexual tendencies. there's nothing wrong with that, its just that i thought a lot of his humor relied on the whole "is he or isn't he" factor.
