One of my favorite sketches, and a popular comedy formula, is to put someone with a mental handicap in some kind of unlikely situation. For example: The retarded gynecologist, the retarded Jesus, the retarded Osama Bin Laden. It works. It's funny. Inappropriate? I dunno. I feel like I'm a pretty good judge of what crosses the line of good taste being that I am retarded. Socially perhaps, but severly retarded.
It seems that England's royal family is running out of money. They are down to just $1. 6 million. Well sure, that's what happens when nobody in your family has had a job for the last thousand years.
