A civil engineer, a chemist and an economist are traveling in the countryside.©OFFICEJOKES.NET

Weary, they stop at a small country inn. "I only have two rooms, so one of you will have to sleep in the barn," the innkeeper says.©OFFICEJOKES.NET

The civil engineer volunteers to sleep in the barn, goes outside, and the others go to bed. In a short time they're awakened by a knock.©OFFICEJOKES.NET

It's the engineer, who says, "There's a cow in that barn. I'm a Hindu, and it would offend my beliefs to sleep next to a sacred animal."©OFFICEJOKES.NET

The chemist says that, OK, he'll sleep in the barn. The others go back to bed, but soon are awakened by another knock.©OFFICEJOKES.NET

It's the chemist who says, "There's a pig in that barn. I'm Jewish, and cannot sleep next to an unclean animal." So the economist is sent to the barn.©OFFICEJOKES.NET

It's getting late, the others are very tired and soon fall asleep. But they're awakened by an even louder knocking.©OFFICEJOKES.NET

They open the door and are surprised by what they see: It's the cow and the pig!
