I'm an insufferable know-quite-a-bit on certain subjects.
I went to a training course in Leeds, in 2012. The Instructor was so impressed he said I should have been doing his job (I'd been doing my job for nearly 5 years, so I had a good knowledge base). I had to bite down on a pencil to STOP blurting out right answers. We did a bit on Asics Running Shoes and I made him go back to the first question (What does Asics stand for? - Anima Sana In Corpore Sano = A sound mind in a sound body), just so I could answer it...
I'll get me coat
