A Fighter pilot is escorting a Cargo plane on along boring mission.
The two pilots were talking over the radio and got into an argument about who's plane was better.
The Fighter pilot said "My Fighter's better Watch what I can do." And promptly completed an intrigate series of manuvers of barrel rolls, loops and other such manuvers.
The Cargo pilot said "Well, my planes better... watch what I can do..."
The Fighter pilot expectantly watched the Cargo plane for several minutes, but the Cargo plane remained flying straight. After a while the Fighter pilot called up the Cargo pilot and said "You didn't do anything."
The Cargo pilot replied
"Sure, I did. I just got up stretched my legs, went to the bathroom and got myself a fresh cup of coffee."
