Hello, I am looking for the title of a Merrie Melodies or Looney Tunes cartoon so I can watch it again.?

The cartoon's plot is kinda sketchy in my mind, but it shows where there is a bunk freezer, and one of the characters (can't picture them - maybe Daffy) comes out of it in disguise as Santa Claus shouting, "Merry Christmas!". As Merry Christmas is being said, he gets interrupted once he realizes he's been caught. Then Porky or Elmer looks at the calendar and it says either April or July. I know there are two cartoons like this, but I already saw the other one where Daffy gets stuffed by Porky.
