Who does that Vonage ad song?
 

The one that goes "Who Who, Who Who Who" over and over.

I feel like it must be a hit song or is it just the world's most infectious commercial jingle? I've gone through stores and heard people whistling "who who who who who" so it definitely is a tune you can't get out of your head.

It's a stupid song by 6,7,8,9's or something like that. Watch Kill Bill Vol 1 and you can see them sing it at the japanese bar.

It's called "Woo Hoo" by the 5.6.7.8's.
