Watch Video From Conan O’Brien’s Fall

Conan O’Brien is back to work after suffering a concussion while taping of a triathlon stunt with Teri Hatcher for last Friday’s show.

Most of the segment was taped outside of the studio, and when the two were running inside through the audience to get back onto the stage, The Tonight Show host slipped and fell backwards hitting his head.

Being the funny guy that he is, he made fun of himself last night over the incident:

“As many of you may know, on this past Friday’s show I was doing a stunt and I hit my head and suffered a slight concussion.  And I promise, if you’re a good audience, I’ll do it again tonight.”

Watch the video above.   OUCH!
