HARTFORD, Connecticut (AP) — Fans are upset after Dave Chappelle stopped his headlining set at a U.S. comedy show because of hecklers and left the stage after telling only a few jokes.

Chappelle was the closing act Thursday night at the Oddball Comedy & Curiosity Festival.

Fans say he stopped his routine after only a few minutes. He sat on a stool making comments about the situation and responding to hecklers until the end of what apparently was his contractually mandated time on stage.

The Oddball Fest posted a tweet asking people to "pipe down and let Dave Chappelle do his thing!"

Some fans say the whole thing was awkward, and some say they should get refunds.

A representative for Chappelle couldn't be reached Friday.
