Eminem made a surprise prank call on Tuesday night on his Sirius Satellite Radio station, Shade 45, to LL Cool J who was a guest on Tony Touch’s “Toca Tuesday.”

Em posing as “Jason from Miami,” challenged LL to a round of “Name That Tune.” Em as “Jason” recited some of LL’s lyrics and LL would have to guess which one of his songs was being rapped.

“Hold your nose, dead bodies are around/ I leave scratch marks under the tears of a clown,” Eminem rapped in character. Cool J immediately recognized his song “Eat ‘Em Up L Chill.”

Em rapped up more lyrics:

“The president woke and he called the pope/ The pope climbed to heaven on a golden rope/ PS. The Lord raised Michelangelo from the dead/ So he can make a fresh painting of my head.”

LL correctly answered: “My Rhyme Ain’t Done.”

Am impressed LL, not knowing he was talking to Eminem said to “Jason” :

“You sound good saying them joints. Damn, B, “that sounds like you need to write some bars, homie.”

Eminem then recited some of his own rhymes from “Lose Yourself” and finally let on who he was. Cool J laughed. Eminem went on to say that he had been a longtime fan of LL Cool J and remembered their only meeting, years ago in a Foot Locker.

“Listen, man, you got this relationship with Dre,” Em said. “You’re cool with 50, so when are we gonna hang out? I got cable at my house, and the game is on.”

Tony Touch the radio host quickly asked Eminem about what he has been up to since he has been on hiatus since late 2006. He was also hospitalized with pneumonia last December.

“Everything is good,” he replied. “I’m just in the studio now working on songs.”

LL Cool J’s next album, Exit 13, is set to drop sometime this summer.
