When we were selling our furniture, a Dutch family came over to view the beds. Their son was like 6'5" and when they left, my sister asked why Dutch people were so tall. My dad told my sister that this was because Dutch people put their children in growbags, to make them tall. My sister believed this for about a year and told just about everyone she knows, including teachers :P She was 9.
He also told her last Christmas that a news flash on Sky News had just told him that Santa Claus had died, after being electrocuted by fairy lights. I'm beginning to think my dads a bit of a sadist :P
