Craig Ferguson's St. Patrick's Day: Fighting With Tim Meadows, Waking Up With Regis (VIDEO)

Craig Ferguson claims to have had quite a St. Patrick's Day. Everyone thought he was Irish (even though he's from that other land mass England screwed over) so they expected a lot from him and his brogue. He delivered.

On the day itself Ferguson hosted comedian Tim Meadows on his show, who, despite the green beer and green tie, didn't know much about the holiday. Meadows was very disappointed to find out Craig was Scottish, because his one man play based on Ferguson's life centered on his Irish heritage. He did, however, make a convincing case for New York becoming a gang-land on March 17.

It didn't stop there. Ferguson appeared on tonight's "Late Show" and discussed the rest of his evening that led to a morning full of Regis Philbin. Of course, that episode was pre-taped on Monday so he couldn't have actually slept with the Reeg...this time.
