Television Memorabilia

Hi I was wondering, is there an age limit on people who go to watch the daily show at their studio in new york???
Colbert's site says 18 years or older for everyone, but the daily show doesnt say anything!!
HELP!!!

Two of my favorites are Noose Hangs High and Naughty Ninetines.

Was born in '64. In the 70s, my family watched this Saturday night line-up on CBS (in this order): All in the Family, M*A*S*H (which I hated) Bob Newhart, Mary Tyler Moore, and the Carol Burnett Show. Best line-up in tv history. Anyway, on the MTM show, there was a really weird laughing guy in the audience. He must have come to every taping of every episode because you could hear his funny laugh on almost every show. Not sure if it was a laugh track. Does anyone remember this? If so, who is that person. I'd love to put a face to that funny, infectious laugh he had! Put those brain cells to work, Old Heads!!!
