Salt

My family makes the best pretzels in the world.
The secret is in how to add the salt. We have a patent on it.
However, a famous patent troll threatened to sue us because he had a general patent on how to salt pretzels.
“I have to preserve my rights,” he claimed. And he offered to license his patent to us.
So, we offered him a tour of our facility.
Five hours later, he was stuffed into a wooden barrel full of shit.
“That’ll preserve you well enough,” I told the barrel.
And we lost it deep in the warehouse.
