An F-16 was refueling behind a KC-135 tanker and ragging on the tanker guys about how much cooler the F-16 was and how it could do so much better stuff.
The tanker captain said, “Let’s have a contest to see who can do the coolest thing.”
So the F-16 went off and did some crazy loops and spins and stuff. Then the tanker guy said, “Okay, here I go.”
The F-16 pilot watched as the tanker continued on in straight and level flight for a minute, then the tanker pilot came back on the radio and said, “There!”
The F-16 pilot said, “But you didn’t DO anything!”
The tanker pilot said, “Sure I did. I went to the bathroom, got a cup of coffee, made a sandwich, and came back and sat down”.
