What should I put on my checks?

How about:

“From Hell’s heart, I stab at thee!”

Barring write-ins, my vote is for “Speak not of my debts,” etc.

When I saw your design, two quotes immediately popped into mind, both authored by Benjamin Franklin:

“In this world nothing is certain but death and taxes.” (letter, 1789)

“Remember that time is money.”
Advice to a Young Tradesman

As long as you fill out the memo line ‘For sexual services’ use anything.

“This check is issued as-is and carries no warranty of any kind for any purpose including, but not limited to, cashing”

Tans: I like it. Don’t know if it would fly by the legal eagles, though, but it could (financially) be worth a try.

You still use checks? The Devil doesn’t take credit?Or lend out money in exchange for the soul?

“Pay to the order of: Sylence”.
– Sylence


And now, for my next trick, I will talk in spooky half-references.

S., what happens when you write one of those checks to someone in your family or heatherlee?
