My very determined roommate found a clip from a November episode of Late Night with Jimmy Fallon where he mentions a news story straight from Uniontown about a woman hiding marijuana in a dirty diaper. The actual news story can be found here and Jimmy's monologue is below. It's the very last joke he tells, so if you're not a fan of Jimmy Fallon and want to skip ahead, it's around the three minute mark.
The thing is, stories like this are kind of common, and I don't just mean drugs. I mean hiding weed in bizarre or terrible places (sometimes involving children) and new uses for dirty diapers.
For example, the guy who hid weed in his kindergartner's Elmo backpack and the woman who smeared a dirty diaper on a car window during a traffic dispute while leaving the county fair. All in the span of a few months.
