Today is Christmas, so I decided to fire up my GameCube and throw in a copy of The Simpsons: Hit & Run, and I was greeted with this:
The halls are decked, and Homer is passed out on the couch in a Santa outfit. Sounds like something to aspire to on a day like today.
Also, I understand that this works on the PS2 and Xbox versions as well, as long as the clock is set to the correct date.
