A couple of F-15s are escorting a C-130 Hercules, 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. The fighter pilots contend that their airplanes were better because of their superior speed, maneuverability, weaponry, and so forth, and pointed out the Hercules deficiencies in these areas.

After taking this for a while, the C-130 pilot says, "Oh yeah? Well, I can do a few things in this old girl that you'd only dream about." Naturally, the fighter pilots challenge him to demonstrate. "Just watch," comes the quick retort. And so they watch. But all they see is that C-130 continuing to fly straight and level.

After several minutes the Hercules 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 Hercules pilot replies, "Well, I got up, stretched my legs, got a cup of coffee, then went into the back and took a leak."
