Cena and Lesnar were on two very different roads in 2003. Lesnar was an established title contender in hot pursuit of the second WWE Championship of his young career. Cena, on the other hand, was a cocky, trash-talking Superstar on the rise who was trying to make a name for himself at all costs.

On the Feb. 6, 2003 edition of SmackDown, a rambunctious, rappin' Cena used one of his patented freestyles to unleash words of fury on "The Next Big Thing." Taking shots at Brock's intelligence, appearance, and even the F-5, Cena challenged Lesnar to a match on the following week's SmackDown. It was a bold move for the former "Doctor of Thuganomics," but it certainly grabbed the WWE Universe's – and Brock's – attention.
