Some animated show (Futurama?) had a scene where a scientist in the future said "Oh, they renamed it centuries ago to stop the teenage giggling" "What did they rename it to?" "Urectum."
Seriously, I had to think before I could figure out why there were giggles. I've always pronounced it Oo-RAN-oos, which is pretty much how it was pronounced in Greek, and how it was pronounced when finally named (it took almost 70 years, and was called Georgium Sidus by William Herschel, its discoverer. A friend of mine who is a retired science teacher, always pronounced it with emphasis on the first syllable, calling it YUR-ahn-us. I pointed out that it wasn't that far in sound from "urinate". Planet just can't get a break. It's the Rodney Dangerfield of the Solar System.
Odd thing about its name is that it is the only one of the seven major planets (not counting Earth) that directly carries the name of a Greek god instead of a Roman one -- if it were named by the same practice as the others, its name would be Caelus. Go figure.
