I was having an argument with a friend recently talking about this episode, but I kept swearing up and down that it was either "Freddie's Nightmares" or "Friday the 13th" which both were on around the same time as "Monsters"
The pool was horrible but the acting was great! I enjoyed it.
By the way, I went to the premiere of Get Smart last night with my sister. We have an "in" at Warner Brothers. It's a very funny movie. I wanted to see James Caan who has a role in it. He was the only featured actor who wasn't there. Bummer. I used to play with Jimmy years ago in Hollywood at The Billiard Den. I would give him the 7 and the break, and race to seven for fifty.
