If you call up the "Dial-a-Carol" hotline any time of day or night, someone will pick up and spread holiday cheer by singing you a carol.

Students at the University of Illinois at Urbana-Champaign have manned the phones every holiday season for 56 years, according to the school's website.

Those who want to get into the holiday spirit can call 217-332-1882. Students will ask what you would like to hear and serenade you.

On the third day of the program, which runs this year from 12:01 a.m. Dec. 10 through 11:59 p.m. Dec. 16, the students had sung 7,000 carols to callers in 50 states.

The group is tallying calls on its Facebook page and said it has already broken last year's record.

NBC4 called and can confirm — the students know all the words to "Grandma Got Run Over By a Reindeer."
