We have bonded over:
Monty Python and the Holy Grail, Caddy Shack, Young Frankenstein, Meatballs, Ghost busters, Airplane, The Blues Brothers, Dumb and Dumber, etc. Women do not get these movies. It is some kind of X / Y chromosome thing. I tell my wife that she just does not have a sense of humor.
Ha! The funny thing is, my kid and I watched these together, then HE got HIS friends interested in them as well, so they perpetuate.
Good stuff, all around.
