If you won $$$, would you say anything or just blow it on yourself

I'de give it to the lady. Women love to get cash. Even though I would make 1/5th of my wife's salary working odd jobs here and there, sometimes I would just cash my paycheck into $20 bills and say "Baby go shopping!". While she was out spending my measly earnings having a great time i was paying the mortgage with our joint account ;).
