Best background story of any rapper?

I used to think Eminem had the most interesting childhood (wasn't just full of gang fights and livin' in the streets, which is interesting of course, but his was different.) Then I came across his nemesis' rapper's music...Cage. Cage has a way more hardcore different childhood (was in a mental institution, etc.) Are there any more rapper's that have crazy interesting background stories like that that are different than the average "growin up in the ghetto"?
