Self-improvement

Self-improvement
 
Brad Pitt once told me
self-improvement is masturbation,
 
but I’ll tell ya, Brad
you don’t have much more
to improve upon.
 
You sure as hell aren’t
masturbating a lot.

Sharp. That said, since "ya" is used in the third line, I think in terms of rhythm and register, "ain't" would be better for the sixth.
