Everyone's gotta start somewhere!

Before Conan O'Brien hit it big as a comedian and late night television host, the jokester made his living doing a variety of odd projects, including this vintage 1986 training video!

On the tape, which was made for the National Association of Music Merchants, the red-head plays an opinionated customer at a guitar store who succeeds in harassing the salesperson.

After airing the tape on Conan, the 51-year-old couldn't hide his embarrassment, telling the crowd, "It's absolutely horrific."

Watch the hilarious video below!
