When I was in kindergarten, my dad told me that he had a pet dinosaur when he was growing up. The very next day at school it was show and tell so, of course, I stood up in front of everyone and told them about how MY dad used to have a dinosaur. I don't know if any of the other kids believed me, but my teacher sure got a good laugh out of it.
