Chances are if you aren't American you have no idea who the freak Tim Tebow is but I will try and summarize. Tebow is the starting quarterback for the Denver Broncos who prays during games; sometimes he goes down on one knee which people have now called "Tebowing." They've even gone so far to suggest since he threw 316 yards in his last game and his favourite Bible verse is John 3:16 there is some divine intervention assisting him.
I'm not going to comment on what I think but I think you can take a guess and instead enjoy this amazing Jimmy Fallon parody. Not only is it an impressive David Bowie impression, but the lyrics and phrasing are great.
