John Davidson is probably most recognizable to Sexy Fandom readers for his role in Edward Scissorhands, where he played (in not much of a reach) a television host. He is probably best known in general for hosting Hollywood Squares through much of the 1980’s. (I kind of liked him in Coffee, Tea or Me?, but I digress.)
Some time in the 80’s, John Davidson did a stunt where he dared ALF to come host his show. Way to get replaced by a puppet alien furball. So, when Hustler made This Aint Hollywood Squares XXX, they were being historically accurate by putting a porno guy in an ALF suit for some furry sex.
