You know, my 13-year-old daughter is brilliant, smart, clever, sharp, and laughs at almost everything I laugh at...Simpsons, Futurama, all kinds of stuff...and I show her the legendary "Parrot Sketch" and...nothing. I think it may be a man/woman thing. I mean, Python....drop dead, kick them in the gut, roll on the floor funny, and not a chuckle. Makes ya think.
I don't know - I have a 13 year old daughter too, and she's a huge Python fan. We watched Holy Grail and Life of Bryan together, and laughed like crazy. She loves it when she finds their old series on television. I may just have to invest in the DVDs.
