50 Cent

I take quarter water 

Sold it in bottles for two bucks, 

Coca-Cola came and bought it 

For billions, what the f**k?

Have a baby by me, baby 

Be a millionaire 

I write the check before the baby comes, 

Who the f**k cares? 

From his 2007 song, "I Get Money."

50 Cent -- who didn't drink alcohol and was a workout fanatic -- was a big fan of the enhanced water called VitaminWater.  When Glacéau, the company that made VitaminWater, decided to introduce a new product called "Formula 50," 50 Cent agreed to an endorsement deal.  But instead of taking his payment in cash, he got a piece of the company.

In 2007, Glacéau was sold to Coca-Cola for $4.1 billion.  50 Cent's payout was estimated at somewhere between $60 million and $100 million.

"Quarter-waters" (which used to sell for 25 cents) were Kool-Aid-like flavored drinks sold in plastic bottles at every convenience store and bodega in the 'hood.  (Formula 50 costs a little more.)  50 Cent's favorite flavor?  Grape, of course.
