This is the exact kind of obtuse argument my brother and I would make as kids.
And GrapeEnvyGuy just emailed me, he and his wife just made Vachel ornaments (with knitting too!), with an accompanying poem. So sweet, check them out. :)
Right lesson, wrong time.
I actually really love gags like this where the reader has to actually visually piece together the joke.
It reminds me of a time, in high-school, when I was removing a fluorescent light from a light in order that it not get knocked out from the party which was going on. I dropped the bulb. Sigh.
