Disambiguation

Last week I realized that I'm officially out of The Loop. In a class, someone made a reference to T-Pain, (as in the rapper, for those of you who are otherwise ignorant like myself). People were throwing this guy's name around without any real context. I decided to jump in on the convo. It went down like this:

Everyone: Blah blah T-Pain blah T-Pain blah
Dodo: T Paine? Are you guys talking about Thomas Paine??
Everyone: ..........

At least Wikipedia knows what I'm talking about.
