Dermot Mulrony, Sean Astin (kinda) and a Manikin - Staying Together - 1989

I think Dermot was contractually obligated to wake up in bed in his tighty whities in his early movies.

                                 Sean Astin - He's definitely in briefs but doesn't show much

 And just to being a ompletionist, the manikin! Besides, I suspect there is at least one person in the            world with a manikin fetish (and for once I am not talking about myself)
