Fuck show money, I spent that on drapes
This line Jay shows that the money he makes from shows is negligible as he spends it on frivolous items like drapes (this also implies that he spends large amounts of money to ensure he has the best there is to offer).
There is also an antithesis between show money as in showing his money and the fact that drapes are used for privacy I.E. stopping people from seeing something.
