Tenureclock and Jabberwock

"Beware the Jabberwock, my son!
The jaws that bite, the claws that catch!
Beware the Jubjub bird, and shun
The frumious Bandersnatch!"

"Beware the Tenureclock, young one,
Don’t pause at night or flaws they’ll catch.
Be sure you publish blurbs, and shun
The populous intro class!"
