Yes, he never actually says what it is, but I think anyone over 12 figures it out pretty quick.
I mentioned "Dr.Demento" on a previous post. For those who don't know, Dr.Demento was a syndicate show that on about 20 years ago which specialized in off-beat novelty songs. I heard and taped some great stuff on that show- songs going all the way back to the 1920s that you would hear no-where else.
By the way, Weird Al Yankovic credits Dr.Demento for being his inspiration and giving him a start on his parody career. Dr.Demento appeared briefly in Yankovic's movie "UHF".
I wonder if I'm the only weirdo here that keeps up with this stuff? :/
