Eminem resurfaced Tuesday night on his Sirius Satellite radio station, Shade 45, to play a joke on fellow rapper LL Cool J, during a segment on Tony Touch's Toca Tuesday show, MTVnews.com reports.

LL Cool J was a guest on the show, when fan calls began to pour in. One caller identified himself as "Jason from Miami." Jason, a self-proclaimed "die hard LL fan" challenged the rap pioneer to a game of Name That Tune with Cool J's own lyrics.

"I don't know if I'll be able to do it, but I'll try … I'll play the game with you! Why not?" Cool J laughed as 'Jason' began to recite rhymes. Cool J immediately recognized the first line from his song "Eat Em Up L Chill."

After two more tunes, an impressed Cool J marveled, "You sound hot saying the joints! That sounds like you need to write some bars, homie! ... You sound good, baby."

The caller then asked if he could rap a song he wrote himself. "Can I drop a little something?' 'Jason' asked. He then began reciting the lyrics to Eminem's song "Lose Yourself," and Eminem's identity was revealed.

"I've been a fan forever," Eminem told Cool J, as they laughed about the prank. The two rappers then chatted on-air, and Eminem asked Cool J when they could hang out. "I got cable at my house, and the game is on," Eminem insisted. "Let's break bread; I'm coming to the house!" Cool J responded.

Although he did not address rumors of his health problems and weight gain, Emimem told the host, "Everything is good. I'm just in the studio now working on songs."
