Learning To Tie A Tie Via YouTube

In an email, Arpie writes: “On Facebook the other day a friend was proud of her 13 year old son who went to YouTube to learn how to tie a tie.  I’ve used YouTube for everything from how to fix a bicycle break to fixing my plumbing.  I know Idaho Dad used it to learn how to drywall his basement.

Question (from Arpie): What is the weirdest thing you have used You Tube for?”
