A baby's gotta do what a baby's gotta do!

And sometimes, a baby's gotta make some extremely grown-up references that fly right over the heads of most of the audience.

Many nineties cartoons are notorious for crass jokes I'm shocked made it past censors, but I always thought of Rugrats as one of the more innocent ones. Well, these ten adult references tell a very different story, and I don't think I'll be able to look at those ingenious babies the same way again.

This is probably the most well-known instance of Rugrats getting a bit raunchy. Grandpa Lou picks up some movies and gets himself his own special treat.

Well, at least he's committed to watching it alone.
