You guys really think that song has something to do with cars?

"Stoker" or "stroker" in that song both conjure up an image that has absolutely nothing whatsover to do with the internal combustion engine. They're interchangeable as double entendres. I thought when you started discussing the "rod length" and "compression ratio" you were getting pretty close to the composer's drift. But then someone brought in bicycles. . .

Sigh
