The 20 Specials of Christmas: The Bob Newhart Show
Like Newhart's comedy, this special takes a little time to ramp up to greatness. The first few scenes are your regular Christmas special cliches: gifts awkwardly exchanged, one member of a couple being more giving than the other, etc.
But once Bob gets into his routine about Christmas parties, the special becomes really funny. Newhart sells well-trodden the tropes of awkward parties and guilt as new and fresh.
