What are the most annoying commercials?

I can't believe no one has mentioned the "identity theft" Citibank commercials. Man, I hate those.

Head On is the only product that can cure the headache it gives from its own damn advertising.

RANCH!!!

From chimpan-a to chimpan-z

Oh, how we miss you Phil Hartman.

Without a doubt Head On is effective since it gives a person a headache.

I can't believe they don't have Mr Whipple and his g*&$#!ed squeezable Charmin'. That guy made me want to stab myself in the eyeballs when I was only about 10 years old.

I am relieved, however, to see the almost unanimous recognition of Carrot Top's lameness. No kidding.

The good folks at Boston.com did spell Jeff Spicoli's name wrong, though, in the Dell dude screen. And that's the most annoying thing of all.

US Army, protect your forehead. US Army, protect your forehead. US Army, protect your forehead.

Seriously though, does this little competition include the pop-ups that appear during our favorite shows? If so, they put all of Cartoon Network on trial for blocking out important parts of the show with their ads, and G4 gets a nod for including explosions that force us to miss what the people are actually saying on the show.

They act like we're not actually watching....

Without a doubt Head On. It is also an incredibly effective ad.

Every time I see those Dr Z commercials, I flashback to the Dr Zaius song from the Simpsons episode with the Planet of the Apes Musical. I don't know what's wrong with me.
