One related to my wife as I never have them. - (he lied)
My wife has always gone a bit overboard with our childrens' birthdays and my eldest daughter's last birthday was no different, even though she is an adult. I on the other hand don't. So for my daughter's last birthday Mrs B bought a cake, decided to decorate it and bought a card which, my wife knowing what I am like with birthdays, was simply put in front of me with the instruction, "Sign there".
Daughter arrives for birthday meal with fiance. During the meal my wife starts to ask about about a butterfly tattoo on my daughter's buttock, which she doesn't have. (Tattoo not buttock).
Slightly embarrassed, (fortunately fiance is getting used to her sometimes quirky ways), she proudly produces, cake, present and card. Cake and card displaying the number 30, when my daughter was only 29!
