The Rolling Stool

At the doctor’s to check out my knee, While I waited until he was free, I glanced up and took note At a sign someone wrote, Which was more a command than a plea. It said, “Please do not roll on the stool.” That’s where doctors would sit, as a rule. Now did some misbehave, Roll and rant in a rave, Thinking doing just that would be cool? I admit that on seeing the sign, That desire somehow became mine, But I’d sure be abashed If I rolled and I crashed, So temptation I had to decline.
