A four ship formation of military fighter jets was at the holding point of the runway at a civilian airport. Behind them, several civilian airliners and business jets were waiting in turn.
Tower: Gunfighter formation are you ready?
Tower: Gunfighter, advise when ready.
Time ticks by with lots of engines running…
Tower: Gunfighter formation, are you ready?
Few seconds later…
Tower: You know, the guys behind you pay for their fuel.
Gunfighter: Roger, they pay for ours too!
