The $20 million Texas Lottery

Tonight when I win the lottery I have chosen cash option, which will leave me with about 10 mil after taxes.
I intend to add a bumper car room to my house. I'll have about six bumper cars and invite people in after (their) work on Fridays for margaritas and collisions.
To add to the fun, I'll paint little slogans on the sides like, "Can you hear me now?" "Lakers 3peat," "Mike Tyson," "Dubya in 2004," "Taliban" and "Martha Stewart."
