"WHAT DOES A YEL LOW LIGHT MEAN?"

What I was thinking is that the actors themselves have done those things.

Judd Hirsch - Antiques shop owner in tv show 'Forever'

Tony Danza - Had a reality show where he taught

Danny Devito - Was an actor/producer in the movie 'Get Shorty' (It could also work where he owns a bar and you get the Always Gang as a cameo)

Marilu Henner - Has written a bunch of books

Christopher Lloyd - Doc Brown, inventor
