I couldn't find the video on youtube but this bit came screaming to mind:

If It Weren't For My Horse
by Lewis Black
So I finished the meal, and I was drinking the boisenberry. Well, because I had to take the edge off the coffee. When from behind me, a young woman of 25 uttered the following—--it was the dumbest thing I'd ever heard in my life until Dan Quayle was elected the Vice President of the United States. She said, if it weren't for my horse, I wouldn't have spent that year in college. I'm gonna repeat that because it bears repeating. If it weren't for my horse, as in, giddyap giddyap, let's go, I wouldn't have spent that year in college, which is a degree-granting institution.

Don't—don't think about that sentence for more than three minutes or blood will shoot out your nose.

The American medical profession does not know why we get an aneurysm. An aneurysm is when a blood vessel bursts in your head for no apparent reason. There is a reason. You go to the mall one day with your friends. Somebody over there says the dumbest thing you've ever heard. And it goes in your ear. Now, you turn around to see if your friends heard it. But your friends are over there, and they're pretending that they're going to buy a cellular phone. And they're not going to buy a celluar phone, because these idiots don't understand what the rate structure means. So you turn back to see who said it, 'cause if you could talk to them just ask them, like, you know, what did you mean by that? But they're gone. And now those words are in your head.

And they stay there. They don't go away. I know you think you're driving to work. But you're not driving to work. All your brain is thinking is if it weren't for my horse, if it weren't for my horse. You sit down and have dinner with your family, and you think you're having dinner, but it's not, it's going woowoowoowoo, how did she get into college with a horse? It's like a mobius strip in your head, it just goes over and over and over for seven days that's all you think about. You don't know you're thinking about it, but you're brain's going overtime, and at the end of the week, they find you dead in your bathroom.
