NO one's dreading tax time more than multimillionaire rapper Jay-Z. "I fire my accountant every year," he tells Playboy. "Every time I pay taxes, he's fired. Uncle Sam did not go in that recording booth with me. . . . It's crazy, the checks I send to the government, for nothing. And then my accountant says, Be happy that you're fortunate enough to cut this check.' Oh yeah? [Bleep] you! You're [bleeping] fired! That's my response. Then I hire him back, because he's right."
