Yes, this is a MST3K Auto

 

Robert Smith made a guest appearance during episode Episode 803, The Mole People, as Howard. Howard was a gift for Pearl from Professor Bobo et al. during Lawgiver Daze. The appearance even warranted a mention on the back of his 2000 Fleer Tradition card. Howard was mute, so it was a non-speaking role.

And it prompted this wisdom from an originally-disappointed Pearl:

"What am I supposed to do with a beefy, virile, muscular, sweaty, servile, well-oiled hunk?"

What indeed.

There you have it!
