A farmer, a priest, and a lawyer were travelling across country when they hit a small town and decided to stay overnight at the inn. The landlord said "Sorry guys, I can only put 2 of you up, but there's room in the barn for one of you." The farmer said "It's my day job, I'll sleep in the barn."
An hour later there's a thunderous knock at the door. The landlord opens it and finds the farmer there. "Sorry mate, your cockerel thinks it's dawn and won't stop crowing, I can't sleep there." The priest says "If it was good enough for our Lord, it's good enough for me. I'll sleep there." An hour later there's a thunderous knock at the door. The landlord opens it and finds the priest there. "Sorry, your cow is pregnant and won't stop lowing. I just can't sleep." They all look at the lawyer until he shrugs and says, "Ok, if I must, I must" and stomps off to the barn.
