No, it's not about jewelry.
While on "Late Night with Seth Meyers" Monday, comedian Louis C.K. revealed that when he was in his 20s and a writer on "Late Night with Conan O'Brien," he tried really hard to get dirty jokes past the censors.
The dirtiest joke, he says, was one he made announcer Joel Godard use during the nightly introduction, a part of the show that was never thoroughly checked out. The joke involved a "pearl necklace," and that's all we'll say. Check out the clip for the full joke, and head to Google after that if you don't get it.
"Late Night with Seth Meyers" airs weeknights at 12:35PM EST on NBC.
