Lil' Wayne has been on his grind in recent years making more guest spots than any other rapper. After selling a million copies of Tha Carter III in one week, it's safe to assume that Wayne's been even busier. 

Weezy might even be so busy that he can't make his Manhattan court date today (August 14) for a weapons charge. TMZ reports:

So we were just told Lil' Wayne is playin' hooky from Manhattan criminal court right now because he has some kind of dental (or possibly medical) emergency that prevents him from driving.
