Would you consider these to be idioms in AmE, or just one-liners in comedy shows?
Of the ones I've seen and heard they are more one-liners and one of the masters of them was Henny Youngman. Some examples: My wife and I always hold hands. If I let go she shops. My wife got a mudpack and looked great for two days, and then the mud fell off. We went to England. There's a 6 hour time difference. When we went to dinner I felt like sex, when we went to bed I was hungry. The hotel had a waterbed. My wife called it the Dead Sea. ....and the list goes on and on.
