Get ready to ring in the holiday season with two colorized episodes of I Love Lucy on CBS!

I Love Lucy is set to air tonight at 8 p.m. ET/PT on CBS, giving older viewers a fun blast from the past and younger viewers a taste of the timeless '60s sitcom. Two episodes will be airing back to back, and instead of the usual black and white, they will be broadcast in stylized color.

The first episode will be The Christmas Episode, which revolves around Lucy, Ricky, Ethel and Frederick reminiscing on the past as the decorate a Christmas tree. They recall Lucy first telling Ricky she's pregnant with Little Ricky, Lucy performing in a barbershop quartet and the day Rick, Ethel and Frederick rehearsed taking Lucy to the maternity ward.

The second episode is the classic Lucy Does a TV Commercial, one of the most famous sitcom episodes of all time. Lucy gets in on Ricky's TV variety show and is tasked with drinking and pitching Vitameatavegamin, which so happens to contain a little too much alcohol. Lucy's speech becomes slurred as she struggles to sell the product. This episode will begin at 8:30 p.m. ET/PT.
