I do have one not-an-SM-skill-at-all on my resume: Juggling. Literally juggling three balls in the air, not the sort of "juggling" we're all doing, all the time.
I read a bit of advice somewhere that I really liked; put one interesting, non-related skill on your resume. It rounds you out as a person, makes your resume stand out a bit, and it gives an interviewer a jumping off point for the dreaded, "So tell me about you, I see you can juggle..."
Also, who knows. I might do a show someday where one of the cast members has to be taught to juggle!
