The only three things a wingman should ever say are:

• Two's up.
  
• Lead, you're on fire.
  
• I'll take the fat chick.

And in a multi-place aircraft, there are only three things the  copilot should ever say:

• Nice landing, Sir.
  
• I'll buy the first round.
  
• I'll take the fat chick.

A new copilot on a bomber was told to only say these three things and to otherwise keep my mouth shut and not touch anything:

• Clear on the right. 
  
• Outer (marker) on the double (indicator) 
  
• I'll eat the chicken. (Crew meals consisted of one steak and one chicken to avoid possible food poisoning of the cockpit crew).
