Your least favorite ad?

I’m about to quit SiriusXM (paid radio) because of the annoying Kars4Kids ad. I always change the channel when it comes on, but sometimes the next two channels are also playing it! SXM must play it more than any other ad they have. Once I hear it, I’ve got it stuck in my head the rest of the day. Plus SXM used to have almost no ads, which is why I initially subscribed. Okay, that’s my rant. What ad do you hate most? Radio, tv, internet, whatever. And rant away!
