 MNM was called up to WWE 's SmackDown ! roster in April 2005 , with Matthews undergoing a name change to " Joey Mercury " . They made their debut during Carlito 's interview segment Carlito 's Cabana , where they interrupted an interview between Carlito and Rey Mysterio , and attacked Mysterio . This provoked a feud between MNM and Mysterio and his partner , Eddie Guerrero , over the WWE Tag Team Championship . Two weeks later , in their debut match on the SmackDown ! brand , they defeated Mysterio and Guerrero to win the WWE Tag Team Championship after Guerrero refused to tag into the match . While Nitro and Mercury held the championship , Melina was placed in an angle with Heidenreich . She publicly mocked him and was the impetus for an attack on him by Nitro and Mercury . In July , MNM were scheduled to face Heidenreich in a two @-@ on @-@ one handicap match , but attacked him before the match started . Road Warrior Animal saved Heidenreich from the attack and as a result , Heidenreich and Road Warrior Animal challenged Mercury and Nitro for the tag team title at The Great American Bash . MNM lost the match and the championship .
