Country star John Rich joined NBC's late night talk show host Jimmy Fallon to perform the comedian's holiday, uh, classic, 'Drunk on Christmas.' Rich donned a Santa Claus outfit and big gold boots to join the cowboy-hatted Fallon for the duet.

Before taking over the 'Late Night' show from Conan O'Brien, Fallon frequently incorporated musical segments, such as the genius 'Idiot Boyfriend,' into his routines.  His Neil Young impersonation quickly became an Internet sensation, and he debuted 'Drunk on Christmas' on air last December, backed by his house band, the Roots.

The only logical thing to do was to up the ante by adding Rich -- originally a member of both Lonestar and Big and Rich, and now working as a solo artist -- to sing of coping with family togetherness with the help of alcohol:

"I'm drinking drinking drinking / I'm gonna drink all day / I'm going home for Christmas and my family's insane / Just gotta make it through the day and there's no other way / Gonna get drunk drunk drunk on Christmas."

You're all free to sit there and pretend you're any better.  Or, you can laugh and nod in knowing agreement. Happy Holidays!
