Nathan Fielder Cracks Up Conan With His NSFW Instagram Prank

Anyone who watches "Nathan For You" knows how dedicated Nathan Fielder is to helping his clients, but nothing can top his commitment to a bit.

Fielder's ability to stay in character came in handy during his "Conan" appearance Monday night, when his deadpan explanation as to why there was pornography in the background of all his Instagram photos had Conan seriously cracking up.

Watch the clip above and remember: always check the background of your photos BEFORE you post them.

"Conan" airs weeknights at 11:00 p.m. ET on TBS.
