Ok, I'm going to head this up by saying I'm from the US. If you don't recognize the commercials, that's why. Regardless, I'm going to post links to all of them.
Ok, let's get things started. I. HATE. SKITTLES. COMMERICALS. They are INCREDIBLY stupid, make NO sense WHATSOEVER, and are just overplayed in general. Like this one:

I mean, what the hell? How does that even work? A Skittles hourglass? Huh?
Second off, there's these weird Glade Plug-In CGI Animal ads. There's an Owl, a Chameleon, I think an elephant....anyway, they look horrible and the puns they use just....just no. Check it out:

And then, I've saved the best for last. Head On. I'm going to guarantee you know what I'm talking about even if you've just heard someone mention it in a forum or whatever but if you ask me, it was the WORST AD CAMPAIGN EVER DEVISED!!! The sad thing is it's SO old, Head On's come out with better commercials, but my local stations keep playing it. It drives me nuts! See for yourself:
