Dwayne Hickman Decapitated?

Just a quick note on the whole Dobie Gillis thing. I dida search on IMDB for the old TV show and came up with: "Bring Me the Head of Dobie Gillis" Obviously poking fun at the old Peckinpah movie Bring Me the Head of Alfredo Garcia, but whoda thunkit? This came out before Tivo, so someone woulda hadda put it on VHS to keep this alive. Anybody out there know where I can score a copy? It's gotta be one of those, so bad it's good kinda shows. Besides, anything's better than reality TV.
