Those fucking Geico commercials.
"Hey honey, I just cheated on you with your sister and got her pergnant, but the good news is, I just saved a bunch of money on my car insurance by switching to Geico!"
Fucking annoying.
Good one
My choice: The Sierra Mist Free radio commercials. Now the SMF TV commercial with Michael McKean and Fred Willard was pretty good, but the radio commercials are awful.
"You want a Sierra Mist Free?" "Sure." "That'll be a dollar" "But you said it was free" (continued ad nauseum for thirty seconds)
or
"Can you buy me a Sierra Mist Free?" "Why would you buy me something that's free." (continued ad nauseum for thirty seconds)
It wasn't funny when they tried that gag in Back to the Future twenty years ago, what makes you think it's funny now.
