Anybody up for a round of find-the-supposed-Twain-quotation?  It's allegedly
something like this: “It is pretty simple raising children until they reach
the age 13. When they reach that age you should stick them in a barrel and
feed them through the knot hole after you have hammered the lid on the
barrel. When they reach age 16 – you should plug the knot hole.”  This is a
very popular Twain attribution in how-to-raise-your-teenager advice.
