The girls may like Justin Bieber, but he likes 'like.' On 'Late Show With David Letterman' (Weeknights, 11:35PM ET on CBS), the pre-teen heartthrob was trying to talk about his upcoming documentary movie, but we couldn't concentrate on what he was saying.

Well, we couldn't concentrate on anything beyond his overuse of the word "like." If anyone tried to play a drinking game based on Bieber's use of the word, they'd be unconscious within five minutes.

Some of our favorite sentences:

-- "Right now [I'm] just kind of like focusing like on my music a lot and stuff like that's really like important to me."

If you haven't watched The Real Housewives of New York City, then you're missing ... well, a lot of really annoying women doing stuff. But you are also missing out on some great wisdom. In the clip below from last night (also at the link above), Kelly explains to her friends her philosophy about going on a date, which apparently includes not eating salad and using the word "like." A lot. Try to keep track of how many times she uses it.

I believe that if everyone would stop using that word so much they would seem 94% more intelligent.
