What is black and rhymes with Snoop Dogg? Dr. Dre

I once challenged Snoop Dogg to a rap battle and the loser had to change their name.

My kid needs me to help him with a report on any famous black scientist. Can we do Dr. Dre?

Snoop Dogg; Shake what'cha momma gave you. Me; Ummm... ok. <vigorously shakes a frozen lasagna>
