Quote from Ross in The One with the Holiday Armadillo
Ross: I'm the Holiday Armadillo! I'm a friend of Santa's and he sent me here to wish you a merry Christmas. Monica: What happened to Santa, Holiday Armadillo? Ross: Santa was unavailable so close to Christmas. Monica: Well, come in, have a seat. You must be exhausted, coming all the way from Texas. Ben: Texas? Ross: That's right, Ben. I'm Santa's representative for all the Southern states. And Mexico!
