disclaimer: this post has nothing to do with scar

as someone who spends some time one the internet, i see a lot of advertisements. lately i have seen a lot of ads that feature a celebrity or public figure (particularly popular: barack obama and britney spears) and says "his/ her IQ is 125, what's yours?". why are these ads suddenly so popular? is the IQ test niche a big money maker?? whats the deal? right now on facebook i have 2, one telling me that lil wayne's IQ is 113 and barack obama's IQ is 130.

also, barack obama comes up as a misspelled word in mozilla spell check. someone needs to get on that.
