The name may be all wrong but still I like the visual

After running at recess, Mr. Argumentative flung himself into the line with the other boys and girls waiting to reenter the building.

Mr. Argumentative (having worked up a sweat):  “Whew!  I ran so fast I was like a snot wad!”

Kindergarten Teacher (trying to comprehend): “Say that again.”

Mr. Argumentative (trying to enunciate better): “I just ran so fast I was like a snot wad!”

Kindergarten Teacher (leaning in closer to the student trying to understand): “How does running fast make you a snot wad?”

Mr. Argumentative (looking at the teacher as if she were the slow kid trying to explain):  “You know.  Like those fast cars guys drive.  Snot wads!”

Kindergarten Teacher (biting the insides of her cheeks to keep from laughing): “Oh.  You mean hot rods.”

Mr. Argumentative (with one eyebrow up and a look of disdain): “You can call them that but my daddy says they are snot wads.”

He just may have a point, eh?
