Good pace, very even throughout, except for the first two lines which stutter a bit.

What do you call something too deep?
Ah! Yes, I have found the ABYSS whence many a poem have perished within!

Why do you even bother, this must have been written in a matter of forty-five seconds.

Sorry, castless should be cast-e-less.
But the current meaning could be interpreted as if the world was devoid of people, or its "cast."

If you figure it out, please say so and I will go to your first poem and comment if you're right.

"LIKE old folks?"
Does this imply that the narrator doesn't consider themself aged?

This question only applies if the narrator is, in fact, old.

There once was poet, a cheat
Who thought he was good on his feet
So he looked and he found
That his distance from ground
Made he journey to hell most complete

(Hee Hee, Ha, Ho, Hah, Ah hah, Heh, Oh ho, *sigh* Not funny)

And I saideth unto Him
"Hurry upeth! You're using all the hot water!"
