U

Remember the ad for 'U' that used to go something like:

guy: Hey you, what's new?
chick: U's what's new.
guy: Meeeeeeee?
chick: No, UUUUUUUUUUUUUU?
guy: Ohh, UUUUUUUUUUUUUUUUUUUUUUUUUUUUU.........

Found it rather redundant the way they kep throwing the word 'u' around, but looks like it worked because I still remember it.
