Here we go for the last time:

My lines:
If you the greatest, then I'm the replacement. Now the truth is out.
Punch-lines turn the roof of your mouth into a basement.//

His lines:You see, I’ll smash ya skull.. Leave a hole n’ it will cave then..
Swing at ya jaw.. turn the ‘roof’ of ya mouth into the basement!

Aint jack shit the same, not the rthyme scheme, not the flow, not jack shit, cept for "roof of your mouth into a basement" which can only be flipped that one way. If you see another way to flip "roof of your mouth" in that rthymescheme you let me know, cuz I sure as hell don't know a way. You're looking at it one way and trtrying hard as hell to make it look liek another way. What's the sense in even discussing it? the 4 bars are apples and oranges.
