"Went to the store, sat on Santa's lap
Asked him to bring my friends all kinds of crap
Said all you need is to write them a song
Now you haven't heard it yet so don't try to sing along
No don't sing along
Monica, Monica, have a happy Hanukkah
Saw Santa Claus, he said hello to Ross
And please tell Joey, Christmas will be snowwwwwy
And Rachel and Chandler, (mumbles something) handler!"
