In a little segment called "41 Irish Terms for Drunk," the actor sipped a pint of beer and schooled us in some little-known Irish-isms, all while trying not to crack up.

Among our favorites:

"Squiffy"
"Boiled in the bag"
"Away with the fairies"
"Lucky-charmed"
"Fanny-packed"
"Steam-pigged"
"Monkey-bottomed"
"Blarney-stoned"

Happy St. Patrick's Day. We're off to get "Moulin-Rouged."
