I am kind of familiar with this show. I saw on Nick-at-Nite commercials for Different World where one girl had a cup on her nose and another asked her Got a date tonight Miss. Piggy?Which episode is this?

the one where Denise had to wear a pig's nose around because she was a messy roommate. I think it's in Season 1

That is from season one. It was one of the funny episodes to me from that first year.
