Balls or ballz?

True Porn Clerk Stories chronicles the life of a woman who, you guessed it, works in a porn rental store. Funny as hell:

“the inevitable similarity of titles makes it a real pain in the ass to look things up. Does the customer want Black Ball, Blackball, Black Balled, Blackballed, Black Balls, Blackballs, Black Ballers, BlackBallers, Black Ballz, Blackballz, Black Ballerz, or BlackBallerz? And does he want the one in the gay section or the one in the straight section?“
