Take this for whatever you want, but listening to the Stern show this morning, former sidekick Jackie "The Jokeman" Martling was on to plug his new iPhone app that has jokes or something on it. Now he's a "dirty" "comic" ("Dirty" because he generally uses swears words or jokes about sexual stuff and "comic" because... well... it's Jackie) so he mentioned something along the lines of "Apple is eventually going to have adult ratings so when that's in there [the App Store I assume] I'll be able to add the dirty jokes".
Edit: Just noticed this now... here's another thread that's discussing the actual app if you're interested.. but F Jackie haha
