After the release of The Final Cut in 1983, chief Pink Floyd songwriter Roger Waters quit the band -- assuming that the others would follow suit. They did not. So when guitarist David Gilmour and drummer Nick Mason started working on A Momentary Lapse of Reason (1987), Waters sued to resolve "the question of rights to the name and assets of Pink Floyd."

In December 1987, Gilmour persuaded Waters to sign an agreement allowing him to use the Pink Floyd name. Waters, however, refused to allow him to use the band's giant trademark flying pig balloons. To Waters's dismay, Gilmour found a solution. "If the pig had been exactly the same as the pig that I designed," Waters later remarked, "I could have stopped them from using it. F--- them..."

That's right. Gilmour simply designed a modified pig -- with giant porcine testicles.
