And you thought that Taco Bell gave you heartburn? Rapper 50 Cent is suing the fast-food chain for using his name without his permission in ads. The company said it would donate $10,000 to charity if for one day 50 Cent became 79 Cent, 89 Cent or 99 Cent—the price of its tacos. But to 50, that figure was chump change. He wants $4 million in damages for "diluting the value of his good name." But they were making 50 more expensive!
