The Simpsons: Mr Plow.
After Homer crashes his car he buys a snow Plow and starts up a successful business until Barney becomes compition for him.
I'm not sure if this was classed as a Christmas episode as there is snow but nobody seems to have any decorations up. This does have its moments of laughter especially Homer smacking his face off the Plow door and painfully responding no when Marge asked if that hurt. (Guest Voices: Adam West, Linda Ronstadt) Season 4 Episode 9.
