"I wish I could punch your idea!"
This episode reminded me of It's Always Sunny In Philadelphia Season 4. Some funny lines and gags, but just a really bizarre story behind it. "Urine, you're out!", the whole milk and "melk" gag and pretty much everything Jay did or said were great, but come on bed wetting? That's even a low for this show.
I get that they're trying to be unique and extreme at the same time, but sometimes less and more and maybe the show could benefit from some overdone plots. You don't have to be original every week to be funny.
