You can buy them custom made.
In Bonita Springs, Florida, a local fire commissioner candidate had his face appear in the restrooms of local bars and restaurants – printed on urinal cakes. One restaurant manager said: "As fast as we find them, we take them out… They’re being replaced in a matter of hours." A resident said: "It’s nasty… But they’ll remember his face." Mr. McCourt lost to incumbent candidate Frank Liles Jr. I don’t know if the cakes influenced the election.
