4-Stroke

My high school shop teacher told me on the first day of class: "The perfect engine does four things--it sucks, squeezes, bangs, and blows!"

Obviously, that caused some immature giggles, but that description stuck with me ever since.

So, for the love of 4-strokes and shop teachers everywhere, buy this shirt--it just might teach the next generation how a good old fashioned engine works!
