Seems kinda cartoonish, but all said, I know people who are actually like that when they're drunk, because it makes people laugh at them. Especially when they were attention-hungry teenagers. Definitely not that much of a stretch. But if you're asking if being drunk makes you act like that, no, it really doesn't. It's all about how individuals react to having their impulses lessened is all. I can see somebody like Korrie just going off the rails.
Also realized I totally forgot to update my RS with the Hancocks. This is now remedied.
