Would you need to clown someone if you sitting on millions? No. And a majority of P's fans dont even know who Yukmouth is or heard the disses towards P from Yuk. Unless Yuk got big and then dissed him I dont see P doing that.
I bet P would knock yuck the fuck out. yuckmouth is only like 5 feet tall. I wouldnt go for the grill tho cuz if you hit either one of them fools in the mouth your hand gonna get shredded by their iced out grills..
