#2 Wiz Khalifa (WWE RAW, March 9, 2015)
World-renowned rapper and songwriter Wiz Khalifa created a few songs for the WWE 2K15 video game. He then appeared as a guest host on the March 10, 2010 episode of WWE RAW to promote the game and his songs. To the fans' delight, Khalifa delivered a memorable medley of his popular songs.
In addition to this muscial performance, Khalifa was also involved in a funny backstage segment. He appeared alongside The Miz and Damien Sandow. "The A-Lister" unsuccssfully pitched an idea for an album called "Miz and Wiz" to the rapper.

Khalifa then introduced Damien "Wizdow" as his newest collaborator. Wizdow presented a rap that hilariously trolled The Miz and this disrespect infuriated the former WWE Champion.
Though Khalifa hasn't returned to WWE programming, his appearance on this show remains quite memorable among WWE fans. Plus, Khalifa's songs for the video game are enjoyable, too. John Cena and the rapper teamed up for two of the songs on the soundtrack, and they're worth listening to.
