GAINESVILLE, Fla. ÷ Sitting in class bored?

What if two guys popped in the door, performed a rap song and ran out before anybody could stop them?

It's happened at UF more than 25 times in the past week.

Sophomores Butch Tanner and Sami Halabi have been visiting classes across campus and singing their rendition of Ludacris' "What's Your Fantasy?" and the traditional "Happy Birthday to You."

"Students are getting extra for their tuition," Halabi said.

Tanner and Halabi said they started rapping "What's Your Fantasy?" a year ago on the Later Gator bus going home downtown. Sometimes they would ride the bus for fun and sing, they said.

They said they had not sung together since last year until they gathered six people two weeks ago at 3 a.m. in the stairwell of the Beatty Towers East, where they both live, so they could sing to them.

They sang on Turlington Plaza later that day, but they weren't getting enough attention.

"The best place to be distracted is in the classroom," Tanner said. "Everyone wants to be distracted in the classroom."

Journalism junior Lauren Dean said she thought it was funny when she walked into her anthropology class while they sang.

"They were really good, except it took a long time for the class to calm down," she said.

Tanner and Halabi said they pretended they were there to sing to one student, always a girl, because the duo thought if they could keep the attention of one student, they could hold the attention of the entire class.
