Ok, I've got to confess, every time my astronomy lecturer say the word 'Uranus' in lecture, I get the giggles.
There are two ways (that I'm aware of) to pronounce the word Uranus. The kinda weird but less entertaining Uran-us, or the extremely hilarious Ur-anus which sounds almost exactly 'your anus'.
The entertainment value should be obvious.
Please allow your mind to interpret these the wrong way:
Uranus is a gas giant.
So, how was Uranus discovered?
Uranus has quite a cold surface...
If we were to take a spaceship into Uranus... (okay so it was actually Jupiter, but it's a lot more entertaining with Uranus)
Uranus is gaseous.
I know it's really quite immature but at least I have fun :D
