If you thought there weren't many jokes about the brain, you'd be wrong. Just check out these funny brain jokes.

Your brain is made up of two halves: the right hemisphere and the left hemisphere, but scientists aren't sure exactly why our brains like jokes so much. What they do know is that if it's a new joke, we're more likely to laugh than if we've already 'got' the punchline or heard it before. You might think a joke about brain function could be dull, but you would be wrong. Just have a go with the ones below.
