I remember asking my dad what a virgin was! It was in the car with my family, needless to say, he got rather stressed! (He never told me though...)
And also, it's not really a question, but when I was younger, my sister and my Dad often spoke german to each other, and the german for thankyou is 'danke'. I used to like saying danke...and making up various words to rhyme with it....little did I know my 'made up' word (beginning with w) was already a word! My dad didn't like that much either!
