Who Is This? Part 25

Okay, this one shouldn't be that tough, but I'll give you a hint anyways.  His most famous movie character had a cool nickname.  Got it, right?  Of course you do.....no?  Damn it, I thought this one would be easy.  Here's another hint for you, dummy.  His most famous movie character had a cool fishy nickname and was a pledge in a crazy fraternity that was on double-secret probation.  Yup, that is Stephen Furst, aka Flounder from Animal House.  You see the resemblance now, don't ya?

So, what has he been up to lately?  Not much since 2006, but he did do over 100 episodes of Babylon 5 and almost 100 episodes of St. Elsewhere, which are both decent gigs.  I've never seen either show, but I've heard good things, plus making over 100 episodes means they get syndicated and that means free money for Stephen.
