With my Brother in Vegas

I ain't behind nobody . . .
So there. I ain't behind you.

I know how to add 2+2 to 4
& sometimes I can triple it
and wait for the score.

It depends who sits the table.
My lead is certain; this ain't no banking game.

If you're looking for some way out,
don't look to me. I know my way.
Some teach, some learn; some march all day.
