Catch some Z

Don’s always trying to catch some Z’s.
No, he’s not sleepy.
He’s literally trying to catch some Z’s.
Don’t ask him why or what he plans to do with them.
It’s no business of yours. It’s still a free country, right?
He puts out Z traps on his lawn.
And checks the traps in the morning.
Squirrels, stray cats.
But never any Z’s.
“Maybe I’m using the wrong bait,” Don says. “What do Z’s like?”
He tried looking it up on Wikipedia, but there were no answers.
And the reddit subpage told him to just go the fuck to sleep.
