George "Pale Kid" Watsky is having a good week. Not only did his video, titled "Pale Kid Raps Fast," hit more than 4 million views on YouTube, but the rapid-fire rapper also debuted on Billboard's Social 50 chart this week at No. 13 and appeared on "The Ellen DeGeneres Show" Thursday (Jan. 27).

During a commercial break while appearing on "Ellen," Watsky stepped up to perform a birthday rap for Ellen, who turned 53 on Wednesday, in a web exclusive.

Watsky, gaining speed with every verse, toasts Ellen with references to Porsches, moonwalking and the Age of Aquarius. How does this relate to the newly-53-year-old? Not sure, but after that harmonica solo, all is forgiven.

In his interview with DeGeneres, Pale Kid talks about his freakishly popular rap, about the acceptance of his future homosexual child, his longing for a Reese's Piece or a Kit Kat, and his gorgeous... knees.
