The master trick is meeting IRS+ client @7PM, save a whole bunch of your client's deduction (that is difficult to argue), play the incompetent moron role as a first your tax clutz by keep saying "Oh, I forgot this"
At 11 o clock the IRS gave up and go home. Client buy beer, I wake up next morning and pass out at my desk after putting up "entertainment" hours in my schedule.
Oh, I made a couple grand shorting EA stock over the years
It paid for my gaming rig of Epicness in 2010.
