The Postal Service versus The Postal Service.

I love amicable legal settlements. This one is perfectly charming:

In 2004, the United States Postal Service sent the band a cease and desist letter citing their trademark on the phrase "postal service". After negotiations, the USPS relented, allowing the band use of the trademark in exchange for promotional efforts on behalf of the USPS and a performance at their annual National Executive Conference. Additionally, the USPS website sells the band's CDs.
