3. Attitude Adjustment To Kevin Federline
John Cena essentially faced a less built version of himself in 2006 as K-Fed made an appearance to promote his new album, Playing With Fire. Federline made appearances on numerous Raw broadcasts. He entered into physical altercations with Cena, the then WWE Champion, during his first. He then came to the ring to aid Johnny Nitro as he struggled against the former Doctor of Thuganomics. After the match the pair squared off, John got up in Federline's face and the former Mr Britney Spears slapped him. Hard. Federline's next appearance came at Cyber Sunday as he dropped Cena with King Booker's World Heavyweight Championship, helping Booker win the Champion of Champions match that also involved The Big Show. K-Fed then took the ballsy move to challenge Cena to a match at the New Year's Day edition of Raw, which of course Cena accepted. Nitro returned the favour alongside Umaga to give Federline the win in this no-disqualification bout. Later that night Cena went after Federline and brought him into the ring and delivered his FU finishing move twice before cameras stopped rolling.
