The long blonde hair woman (think 70's hippie free-love type) come up and tells her old boyfriend that she has a 17 year old son that she never told him about, and that he's run away.  Then she goes up and tells another old boyfriend the same story, including the part about the boy being his.

In trying to track down their long lost son(s), the men meet up and realize that she told both of them the same story.  But they are determined to find the kid anyway.  After a few pretty funny incidents, including the misconception of a bizarre improper relationship, they finally get the boy home.

The mother admits to the boy that neither man is his real father and that her husband who he grew up with always was.  He went out and told the other men separately that they were each his father and they left happy.

Kinda funny.   I don't think either Billy Crystal or Robin Williams would count this among their top movies.  Although it's a lot closer to Billy Crystal's movies than Robin Williams. 

Mel Gibson makes a great cameo as a drugged-out pierced tattoo artist groupie guy.  I almost didn't recognize him and probably wouldn't of except for his very unique voice.  It's Mel all right.  I had to back up and watch it again.
