I taught myself to tune in to another persons wavelength, figure out what they were looking for, and try to project that thing back at them.
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.
