A young woman joined the army and signed up with the paratroopers.

She went through the standard training,
completed the practice jumps from higher and higher
structures, and finally went to take her first jump from an
airplane.
The next day she called home to tell her mother the news.

‘So, did you jump?’ asked the mother.
  
“Well let me tell you what happened” the girl said.
 “We got up in the plane and the sergeant
 opened up the door and asked for volunteers.
About a dozen people got up and just walked out
of the plane.”

 “Is that when you jumped?” asked her mother.
  
“Uh, no. The sergeant started to grab the
other men one at a time and throw them out the door.”
  
”Did you jump then?” asked her mother.
  
“I’m getting to that.
Everyone else had jumped and I was the last one left on the plane.
 I told the sergeant that I was too scared to jump.
 He told me to get off the plane or he’d kick my butt.”
  
“So did you jump?’

 “No. He tried to push me out of the plane
 but I grabbed onto the door and refused to go.
 Finally he called over the Jump Master.
The Jump Master is this great big guy about six-foot six, and 280 pounds.
He said to me “Are you gonna jump or not?’’
  
I said ‘No sir, I’m too scared.’”
  
“So the Jump Master pulled down his zipper and took out his Johnson.  I swear Mom it was
about ten inches long and big around as a baseball bat!
He said ‘Either you jump out that door or I’m sticking this bad boy right up your
 ass.'”
  
“So, did you jump?” asked her mother.
  
A little at first.”
