Notre Dame Class of 2016 Tommy Brennan -- made his Saturday Night Live debut this weekend...
Catch him saying GO IRISH! -- as he's signing off.
I found out after posting this story that Tommy was student body president his senior year at Notre Dame -- as was his Dad in the early 80's. He started doing stand-up at some Open Mic places in Chicago...
Was told "he bleeds blue & gold."
Here is Tommy's Tonight Show debut four months ago...
