Keeping a secret

Farmer Josh killed a pig and hung it up for the night, intending to butcher it in the morning, but the next day it was gone. He didn't tell a soul about it, and nothing happened for more than two months.

Then another farmer, who lived down the road, came by and said, “By the way Josh, did you ever find out who stole your pig?”

“Nope,” said Josh. “Not until just now.”
