Happy Christmas, Mr. Worry! is the 4th episode of the second season of Mr. Men and Little Miss. It was first broadcast on 10 February, 1996.
It's Christmas Day and all the Mr Men and Little Miss are thrilled. That is, except for Mr. Worry, who is worried whether all his friend's houses have a Christmas tree beautiful enough to welcome Santa Claus; for he mustn't be disappointed at all costs!
So, with the help of Mr. Strong, Mr. Worry takes round magnificent Christmas trees to all his friends. The next day, everyone has received a present from Santa Claus and they all thank Mr. Worry for his help, only to find him already worrying about the next year's Christmas.
