Darling, won't you ease my worried mind?

A cow walked into a jewellery shop and asked
the owner,

"You got any grass?"
"No, sorry"
"Okay" and it walked out.

The next day, the cow again went into the shop
and asked the same question, and got the same
reply.

This went on for the next couple of days, until the
owner, cracking under pressure and threatened
the cow as it came into store,

"If you ask about the grass again, I'll tie you up
and slit your throat!"

The cow ran away, and didn't return for a couple
of weeks. The owner went about his usual ways.

One day, the same cow came into the shop and
asked the owner,

"You got any ropes?"
"No"
"Okay, you got any knives?"
"Err, no"
"Okay......................................You got any grass?"
