This is so fun. Its a hotline you can ring 24/7 to get a Christmas carol played from a living breathing human being. Its put on by the University of Illinois each year and they have been doing it since 1960! It's completely staffed free of charge by volunteers!

The number 217-332-1882.

A quick paste from the Snyder Hall blog roll confirms:
"I'm a student from the University of Illinois and I just wanted to spread the word about a 24hr Carol Hotline that we students run during our finals week before winter break.

The Carol Hotline is called Snyder Hall "Dail-a-Carol" and it is a free, non-profit, just for fun volunteer hotline run and staffed by the Students that live in the Snyder Hall dorm at U of I. Basically, the jist of the program is, anyone is welcome to call our number and request us to play them a Christmas carol or winter holiday song out of our stock of CDs. It is just a fun way to get into the holiday spirit. No one makes any money, and it doesn't cost you a dime apart from whatever your phone company likes to charge you for making calls.

So if you feel like hearing a carol give us a call at 1-217-332-1882"
