Now that you've been warned, I present two ads that are guaranteed to cause a stir on the Internet.

Sometimes, you can't make this stuff up. Sometimes you do, put in on YouTube, wait for for the Internet to get angry and watch the revenue roll in.
I'll bet you can't figure out which route PMU took.
