An Iowa fan was driving to Lincoln and saw a sign "Clean Restroom". He got out of the car and cleaned it.
Got back in the car and continued to drive. He then encountered a sign that said "Lincoln Left". Understanding the sign, he turned around and drove back home.
Arrinving at home, he called the airline and asked how long did it take to fly to Lincoln. The operator, said "one moment sir". He said thanks and hung up.
