The former Tonight Show host can be seen washing a dirty desk in his driveway in the 30-second clip as he prepares for next month's Conan premiere.
A message posted on his official Twitter account said: "We've just released a brand new TBS promo of Conan that has to be seen to be believed! We hope you like ROCK."
The 1980s-style video - which is the first promo to feature the comedian - shows O'Brien writhing around on his desk in the water and suds while playing with a hosepipe to the tune of Def Leppard's 'Pour Some Sugar On Me'.
Conan will premiere November 8 at 11pm on TBS.
