There is a new iPhone app called "I am T-Pain" that auto-tunes whatever you say into the microphone. Last night, to promote the app, T-Pain recorded an Obama healthcare mashup much in the style of the viral video series, "Auto-tune the News" (in which the artist recently starred).  The ending shot is of a grill superimposed onto Obama's teeth, which twinkles along with T-Pain's when they smile.
