Conan O'Brien was back and well on Monday night,

showing his head injury video from Friday

Tonight Show the night he was sent to the

hospital.

O'Brien was doing a skit with Teri Hatcher - a

triathlon, and culminating with Hatcher

O'Brien races for the finish line

study.

Conan slipped just before the finish line and

hit the back of his head hard - but still

had the presence of mind to request the immediate

reproduction.

Then, O'Brien said, he ran backstage to change

clothes and prepare for the next segment

Seth McFarland - but when it came Conan

back to your desk to read the blue card of notes,

he said he could well have been reading a

foreign menu.

Conan said he just kept wanting to do the show.

His memory of the following events are obscured,

Conan said, but his colleagues around him,

and medical experts made him simple questions

as the year that the president and such,

and when Conan said, "I know it's not 2011"

they knew it was time to take O'Brien

hospital.

Conan ended up thanking his mate Andy, who

said kept him on points all the time, and

O'Brien also thanked the paramedics and the Cedars

Gente de Sinaí.
