No, Catspaw is having you on, without the laugh you claim Americans need to have to get it.Might also mention Dave Allen and the fact that BBC has been very successful in launching a new cable channel, BBC-America, as they've found a ready made and avid audience for the *dry* humour you note, here, in the States. Believe it or not, some of us in America grew up with that exact same sense of humour. Generalisations should be avoided like the plague.
People are people are people are people....but some of us wish to be cats.
