In this episode, Jan has signed up for the local talent show and she is looking for someone to watch and let her know what they think. None of the other boys will watch, but Greg, being the groovy kind of guy he is, agrees to be the audience. Jan breaks it down like only a Brady can, but maybe she is taking this routine a little far. And now that Greg is totally disgusted by what he saw, he has no problem telling her exactly how hot Marcia is. Marcia, Marcia, Marcia!
