It’s obnoxious, but I still love that Priceline commercial with the Asian couple and Bill Shatner:
“But you must say everything I say exactly how I say it.”
“Honey…”
The actor’s mimicry of Shatner is perfect; I just love it. Can’t get enough of that commercial; I giggle like a schoolgirl every time it’s on. I think it drives the Mr. nuts how much I’m tickled by it.

More than 60 posts, and no mention of Flo the Progressive Insurance chick? I’m flabbergasted.
The reason I didn’t mention Flo is because she’s already had at least one whole, multipage thread dedicated to her.
Without Flo, the commercials themselves are nothing special.
Amazingly hot girl in a commercial I’ve never heard. Just hit the mute button and enjoy.
I have no idea how I’ve forgotten so many of my favorite commercials. They are even saved in my YouTube account fer cryin’ out loud! Just goes to show how often I actually sign in huh? 
I really like the American Express Purchase Protection ad - so pretty, so clever!
Old Spice “I’m a Man”
OK, I get an excerpt from Rudolf.
I love the shankippotamus commercial.
I also love the original Sonic Guys commercials. My favorite has to be Cheap date.
Cure Auto Insurance commercials, especially this one:
Too lazy to link it, but for some reason I never tire of the Gamefly commercial where people are shown freaking out (yelling, screaming, wrecking furniture) over getting a bad game. NO idea why it cracks me up so much, but I can’t help it; I get giggle fits every time it comes on.
Or however that is spelled.
Never fails to make me laugh!
“401 K tanked…”
“Why don’t you try reading the rule book…?”
Yup!
That’s the one!

Jumbone!
Two from Sprint Mobile that I always thought were clever.
