Teller Teller

On one of the magic blogs, or news sites, it posted a link to an article from a news paper. Sorry thats a little vague, but I don't remember the site, nor the paper, however the site had a picture of Penn and Teller, with a caption that read something to the effect of "Penn Jillette and partner Joe Teller work on a new trick"

The magic blog had the headline "Teller's first name revealed"

whoopdy doo.

I have 2 problems with this...first off, its wrong...

Check out Teller's bio on IMDB
His birthname is Raymond. Joe, is his father's name.

Secondly, it says, Teller legally changed his name to...Teller, and his driver's license and passport both only say "Teller"

So what is Teller's first name?

Teller.
