Before you start you can see the spaces like this "-" between the numbers so I 
recommend you to slap the strings as Bruno Mars slap the guitar

Do this in verse 1

[Travie McCoy]
     A[1 strum down]
I’ll be playing basketball with the President
Dunking on his delegates

    C#m7[1 strum down]
Senator … his political etiquette
     F#m 
Toss a couple milli in the air just for the heck of it
    E
But keep the fives, twenty’s …completely separate
  A
And yeah I’ll be in a whole new tax bracket
  C#m7
We in recession but let me take a crack at it
  F#m
I’ll probably take whatever left and just split it up
  E
So everybody that I love can have a couple bucks
  A
And not a single tummy around me
  C#m7
Would know what hungry was
  F#m
Eating good sleeping soundly
I know we all have a similar dream
  E
Go in your pocket pull out your wallet
And put it in the air and sing
