i wish TV ads had a special identifier, so when watching a video via playback you had the option on the remote to "skip" ads altogether rather then seek through them.
The Progressive commercials with Flo are like fingernails on a blackboard. On the other hand, the State Farm guy doesn't bother me at all.
The Geico squealing pig is so insane it always makes me laugh, as does their drill sergeant/therapist and those woodchucks. The wallet-and-phone one and the Lincoln one make me smile. OTOH, the Antiques Roadshow parody is just lame.
