Paul has certainly brough a more metal edge to Meat's work since joining the band, and HIHB was a great album, so I think his increasing envolvement has been a good thing.
As for Lil Jon, when I win the lottery i'm going to pay a group of ex special op mercenaries to do a special job.
They will sneak into Meat's house, and into Lil Jon's in the dead of night. Once there they will sew
very powerful magnets into the seams of every pair of underpants they can find. This will ensure that Meat and Lil Jon are kept at opposite ends of the planet at all times
