[smoothsailing]

Gloom, despair, and agony on me
Deep, dark depression, excessive misery
If it weren’t for bad luck, I’d have no luck at all
Gloom, despair, and agony on me.

(Apologies to Buck Owens and Roy Clark)

And, the adaptation from my college days:

Gloom, despair, and DiffEQ on me
Deep dark depression, excessive misery
If it weren’t for DiffEQ,
I’d have a 4.0
Gloom, despair and DiffEQ on me!
