"The Dentist" series of cheesy horror movies starring Corben Bernsen. Really funny stuff. Corben should always be typecast as an insane person since he was so good in these movies.
Also the "Return of the Living Dead" horror/comedy movies that came out in the 80's. (except for part 3)
These 2 guys were great.
