A couple of F-15's are escorting a huge C-130 Hercules transport plane, and their pilots are chatting with the pilot of the transport to pass the time. Talk comes around to the relative merits of their respective aircraft. Of course, the fighter pilots contend that their airplanes are better because of their superior speed, maneuverability, weaponry, and so forth, while the putting down the transport's deficiencies in these areas.
After taking this for a while, the transport plane pilot says, "Oh yeah? Well, I can do a few things in this old girl that you'd only dream about." Naturally, the fighter jocks challenge him to demonstrate.
"Just watch," comes the quick retort.
And so they watch. But all they see is the C-130 continuing to fly straight and level.
After several minutes, the transport pilot comes back on the air, saying, "There! How was that?"
Not having seen anything, the fighter pilots reply, "What are you talking about? What did you do?"
And the transport pilot replies, "Well, I got up, stretched my legs, got a cup of coffee, then went back and took a leak."
