I like "The Christmas Tree Lot" but I am willing to bet a lot of you like "Busy Christmas"

I like

The Miracle
Lost Christmas Gift
Day After Christmas
Busy Christmas

the most... but I love them all :)

Definately a toss-up between The Miracle and Busy Christmas. But, I ♥ them all, too :)

I like "Busy Christmas" (particularly the 1964 airing with Rick singing "The Christmas Song" with all the Nelsons present, including Tracy and David and June's son Danny) and "The Christmas Tree Lot." In the latter episode, the scene where Ozzie plays Ricky's guitar and sings at the lot and the conversation that follows b/w Rick ("Hey, Pop sounds pretty good") and Dave ("Didn't you know? He was the Ricky Nelson of his day!") is one of those priceless blurring-the-lines between real life and fiction moments that among sitcoms would only work and be funny on The Adventures of Ozzie and Harriet.

I LOVE them all!...but...if I have to pick I'd choose Busy Christmas.
