As I'm sure you know (right?) the U.S. invaded the Caribbean country of Grenada in 1983; we didn't like their non-aligned new leader (who put an end to corruption, etc), so he swung left and got help from Cuba. We invaded in '83, and lost 42 soldiers, while killing 70 Cubans and 170 Grenadiens. (Be warned: this is all setup for a tasteless joke). Of those casualties, 18 occurred when we mistakenly bombed the island's only mental hospital. I can just picture the inmates... "Am I crazy, or are the Americans bombing us?!?!"
