A fighter pilot was zooming through the stratossphere when he spotted a transport plane plodding along far below. He slammed on the brakes and went down to plunk along slowly beside it.
"Your job must be really boring," he said over the radio.
"No, actually it's the best job in the world", the transport pilot replied.
"Oh yeah? Watch this." The fighter pilot slammed his throttle wide open and threw his fighter into a vertical climb; then he proceeded to do a series of barrel rolls, snap rolls and loops. Finally he pulled into place beside the transport again and said, "Beat that."
"Okay." The transport flew straight and level for fifteen minutes. Then the pilot came back on the radio and said, "Beat that."
The fighter pilot was baffled. "But you didn't do anything."
"On the contrary," the transport pilot said. "I went to the bathroom; then I made a sandwich and a cup of coffee and checked my email. Beat that."
