What is the weirdest commercial you've seen while watching MLP?

Specifically, what commercials have come on while you were watching MLP, on TV or online, were the least fitting commercial to go with what you were watching. For example, earlier today I was watching Baby Cakes, and in the middle of the episode, a commercial for a certain thing that starts with "c" and rhymes with "ondoms" came on. I was disturbed. So, what about you guys?
