Before They Were Stars [VIDEO]

Each Tuesday night at 7,  I host 'Trivia Night' at MacFarlane's Celtic Pub. One of my favorite things to do is hold up pictures of celebrities before they were stars and see how many teams can name them. Sometimes, it's pretty easy, but some stars have changed so much that it's almost impossible.

Here are 25 stars in a series of clips all taken before they became major movie, TV or recording stars. You won't believe the clip of Sarah Jessica Parker at about 1:45!
