A man and his wife were going to a costume party at a rural mansion.

Just in sight of the mansion, the car broke down.

They decided to
walk.

Since the shortest distance was across a pasture and they were going
as a cow, they decided on the short cut.

About halfway across the
pasture, they ran into a bull who became very "interested."

The
husband, who was in the back, said, "What shall we do now?"

The wife, who was in front, said, "I'm going to put my head down and
make believe I'm eating grass. You had better brace yourself."
