Spring Forward, Fall Back

One important lesson every beginning mechanic must learn is: "Lefty loosey, righty tighty."

To which I reply, "I before E except after C, and when sounded like A, as in 'neighbor' and 'weigh'."

Also:

Thirty days hath September,

April, June and November.

All the rest have thirty-one, save February,

Which one year in four has one day more.

How can anyone forget that?
