And a sidenote for you, Eminem & Proof weren't f**king "best friends forever" or nothing; they were cool from high school onwards. Kinda like some other famous rap friends...oh wait, that would be Jay & Biggie.
Nah from what i understand, Proof and Em were more like brothers. They met each other in the late 80's when Em was getting picked on alot. Proof's mom said that Em was going through a hard time so he was staying with them for a while, "she considered him like a son". Proof used to let Em wear his clothes and everything. So i dont think you can compare Biggie & Jay's relationship to Proof & Em's.
