You could spend hours learning first aid in a stuffy lecture, or you could watch the weird and wonderful videos of Dr Hamstar.

The good doctor is an Aussie in a loud lime green suit who teaches first aid backed by a throbbing dance beat. He can’t sing very well, or dance any better, but you’ve got to admire his enthusiasm. He feels a lot like the embarrassing uncle at a wedding!

They say one of the best ways to teach anything is to present it in a song. But I’m not sure they had something this outrageous in mind.
