Awful Comedian
YouTube
I found a video of an awful comedian. And then I found some more.

The last time I performed on stage was a 4th grade production of The Velveteen Rabbit. I was the Skin Horse. I forgot all my lines and probably cried. So I give these guys a lot of credit. Keep on chasing that dream.
The Bartender
Don't listen to this clip with headphones. His heavy breathing will gross you out.
Daniel Songer
We covered this guy last year, but that won't stop me from spending all afternoon watching his back catalog. He sings, he dances, he raves incoherently. He's up to 133 videos at this point.
Darrell Bluett
Probably the most popular bad comedian on YouTube, Darrell just wants to tell some interesting stories.

Oof. *Cringe*.
