Heads, Tongues, cures for baldness, sick all over the floor, Theme Hospital must have been painstakingly modelled on our local infirmary where these types of ailments are common. If you have never played Theme Hospital then you must give it a go. It's a great 'management sim' style game with loads of humour thrown in.
The receptionists voice over the PA system is perfect, the way you can eject patients that are about to die so that they don't affect your stats is classic. Whilst most of the diseases are fictional, I'm sure I knew a guy with Hairyitis once, when he got changed for football he was still wearing a thick black jumper under his Shirt.
Our shirt here depicts a poor chap suffering from the agonising "Bloaty Head" syndrome, so it's off to the inflation clinic for him to painfully have his head popped, then re-inflated a bit to the correct size.
