Bizarre: Strother Martin's quick nude scene!

After aquiring the last boy for the convenant, the ceremony begins and Martin goes out to the younger 'witch' and has her recite her prayers to satan. For a brief moment (had to do slo-mo to catch it) you can see Martin doning his birthday suit as he opens up his cerimonal robe. His gut is hanging out and the angle hides his 'equipment', but definitely he's in the buff for a couple of seconds of screen time.
