An F-15 pulled up alongside a C-141 up in the flight levels and managed to contact the cargo plane on the radio. After chatting a while, the fighter pilot said, "Hey, watch this!", and proceeded to do a barrel roll around the C-141.
The C-141 pilot was duly impressed, and called back, "That's nothing. Watch this..."
After two minutes of stright and level flight, the fighter pilot couldn't stand it, and said, "OK, what did you do?".
The C-141 pilot said, "I just got up, walked back to the restroom and took a piss, stretched my legs for a while, then got a cup of coffee."
Some men do belong behind a flying desk. LOL
That's a classic.
