It's enough to make some people's stomachs churn just looking at it.
But today, students at Park Christian School in Moorhead found out who is the reigning champ of chugging egg nog.
Junior Josiah Militzer faced off against last year's winner, senior Scott Schwandt.
The underdog came out on top today.
Militzer managed to chug down an entire quart of the festive drink in about 15 seconds!
The contest has become an annual tradition at Park Christian.
Hopefully it wasn't followed up by an impromptu race to the bathroom!
