A C-130 was lumbering along when a cocky F-16 flashed by. 

  
The jet jockey decided to show off.   

The fighter jock told the C-130 pilot, 'watch this!' and promptly   
went into a barrel roll followed by a steep climb.  
He then finished with a sonic boom as he broke the sound barrier. The F-16 pilot asked the C-130 pilot what he thought of that?   

The C-130 pilot said, 'That was impressive, but watch this!' 
    
The C-130 droned along for about 5 minutes and then the C-130   
pilot came back on and said: 'What did you think of that?' 
    
Puzzled, the F-16 pilot asked, 'What the heck did you do?' 
  
The C-130 pilot chuckled. 
 'I stood up, stretched my legs,  
   walked  to the back, 
 took a leak, 
 then got a cup of coffee and a cinnamon roll.'
