Ah, yes. I should have known that Dave would nail it quickly.

“Tourist Trap” (1979)
Directed by David Schmoeller.
With Chuck Connors, Jocelyn Jones, Jon Van Ness, Tanya Roberts, Robin Sherwood, Keith McDermott, Dawn Jeffory.

A group of teens on vacation get stranded in the middle of nowhere due to some mysterious car trouble. They are helped by Mr. Slausen (Chuck Connors), owner of Slausin’s Lost Oasis (a museum filled with animated mannequins). As their friends begin to disappear one by one, the remaining teens must avoid the attacks of a strange man in a mannequin-like mask in order to escape a fate worse than death.

Nice little horror gem that works especially well if you find mannequins to be the least bit creepy.

Sheesh, Homer. Hopefully your last date didn’t look like that … you handsome fella ya!
