Professional French motorcyle rider Erwan Nigon (AP/Michel Euler) Commercials for erectile dysfunction medications like Cialis end with a warning that an individual should contact their doctor if they have an erection that lasts for more than four hours. After 20 months, Henry Wolf decided to contact a lawyer instead, claiming that the seat on his BMW motorcycle gave him an erection lasting nearly two years. The San Francisco Chronicle reports that Wolf filed a lawsuit against BMW North American and Corbin-Pacific claiming that the "ridged seat" on his 1993 motorcycle left him with mental and emotional anguish after allegedly causing an extreme case of priapism, also known as a long-lasting erection. Wolf "has been experiencing continuing problems since his motorcycle ride," attorney Vernon Bradley of Sausalito wrote in the lawsuit, which was filed in California Superior Court in San Francisco last Thursday. "He is now unable to engage in sexual activity, which is causing him substantial emotional and mental anguish."
