A friend of mine is a bit of a tinkerer and a has literally every powertool you could want. He often helps me fixing my bike and car bits and I often help him with his car bits and pieces too. Anyway he came round lend me his socket set and he brought round his spudgun that he had invented.
We then thought it would be a good idea to fire it at him!
