Actor Jamie Costa apparently decided to film this scene in which he plays Robin Williams from 1982. If you ever watched Robin Williams, I think you will agree that not only does Costa have an amazing resemblance to Robin Williams, but he nails all of the mannerisms of the late actor.
In this clip, Williams finds out about the death of friend John Belushi after having spent time with him the night before, as he and Pam Dawber have a Mork & Mindy screen test together to see what a scene looks like. Costa even has a Mork costume hanging on the wall that he forgot to put on.
