Somebody said that it couldn’t be done —
But he, with a grin, replied
He’d never be one to say it couldn’t be done —
Leastways, not ’til he’d tried.
So he buckled right in, with a trace of a grin;
By golly, he went right to it.
He tackled The Thing That Couldn’t Be Done!
And he couldn’t do it.

03/26/2024 This seems to be a reply to Edgar Albert Guest’s poem “It Couldn’t Be Done.” A couple of readers recognized it from The Dick Van Dyke Show (“The Return of Edwin Carp,” April 1964), but I don’t know whether that’s where it originated. (Thanks, Kevin, Chris, and Seth.)
