In 1272, the Arabic Muslims invented the condom, using a goat's lower intestine.
In 1873, the British refined the idea by taking the intestine out of the goat first.
This ties in nicely with my (very quickly put down IC's memory hole) thread from yesterday about the dolphin masturbating with a dead fish. Apparently, dolphins prefer the intestines to remain where they are... You should've seen the look on that dolphins face..... dirty bastid.
