Stephan Colbert is a teacher, has a golf course house on a hill. The house has streetcar tracks leading up to it. Then old tracks are buried due to the very steep slope. His neighbors, who live on opposite hills like in the Palm Springs mountains, shoot golf balls at him. But the golf balls are actually small fighter jets that get shot down by his fighter jets. If you think normal aviation is expensive, try repairing ridiculously tiny planes that have been shot at, in mid-air.
