The suspect mayfly

A lazy mayfly, arrogant and wayward,
Resolved to fly to see his friend in Hayward.
He bought a ticket, first-class, on United,
But, at the airport gate, a guard recited,
“No luggage? That's suspicious. And, in fact,
You must be searched -- so says the PATRIOT ACT.”
For hour after hour, while he raged,
They probed and scanned the mayfly -- and he aged!
A mayfly's life lasts only days at best,
And less, when he's denied his hourly rest.
So, when the guards had finished their routine,
He was a grizzled insect, bent and lean.
Now moribund, he staggered to the gate,
And hope his scheduled flight would not be late.
The agent checked his papers, gasped, and cried,
“You can't go! Wait right here!” And, as he died,
The mayfly asked, “What's wrong?” The agent hissed,
“No flight for you -- you're on the NO-FLY LIST.”
