When Ross's son, Ben, is staying with him over the holidays, he decides to take advantage of the opportunity to teach him about Hanukkah and their Jewish heritage. He entices him by promising that Santa Claus will also make an appearance, but quickly realises he's too late in ordering a Santa suit and settles for dressing as the "holiday armadillo" when costume pickings are slim.
What to wear: An armadillo costume, such as this one, available on Amazon.
