Last week, a new beyond hilarious competition show called Killer Karaoke debuted on truTV and it's quite possibly the most awesome thing ever. At least that's what Carrie Underwood thinks!

The country star Tweeted, "This is the most awesome thing I've seen all day. Laughing so hard now," after seeing a contestant attempting to sing Before He Cheats while enduring Karaoke's killer obstacle course.
