It's hard out there for parents who want to teach their kids about important issues. Dad Will Reid found there was only one way to get through to his teens about one of them.
After so many years of discovering an empty toilet paper roll in the bathroom, he made a very clear instructional video.
"Obviously, me telling them [something] face to face is not working," he says.
Naturally, the clip has gone viral, and Dad promises many more instructional videos to come. Perhaps in the next installment he can settle the age-old TP debate: over or under?
