This is a shirt from that weird period where The Undertaker suddenly stopped being an undead zombie and started being a bad ass redneck biker.

Apparently this was just a phase because he went back to being an undead zombie later.
“Deadman Inc”?
Well, I guess that makes more business sense than “Deadman, LLC”.
You have to protect your assets, after all.
Can you imagine trying to get a loan from the bank when your business is called
Deadman Incorporated”?
“Mr. Taker, what do you produce that would tell us this business is a good investment for our bank?”
“Uh… I ride around on a motorcycle and beat people up?”.
“I see.. Well, that seems like a sound business plan. Approved!”.
