Two back-to-back classic episodes of the 1950s series I Love Lucy are featured in the I Love Lucy Christmas Special on CBS Wednesday, Dec. 23, at 8pm ET/PT. This year the “Christmas episode” (first presented in December 1956), now colorized in its entirety, is paired with the newly colorized “Lucy Does a TV Commercial” (a.k.a. “Vitameatavegamin,” first broadcast on May 5, 1952). The two episodes are seamlessly combined into one set with no interruption between the episodes.
