Alligator

SNAP goes the camera by the couple on the bank.
“Look at his smile, look at his grin!
He’s so dashing—I wish I could tickle his chin.”
“Let’s get closer, just a step or two… can’t hurt.”

SNAP goes the alligator, licking his long, wet chops.
“Mmm. Peace at last,” he thought.
“Once there were three.
Now it’s just me.”
