As the bus stopped and it was her turn to get on, she became aware

 that her skirt was too tight to allow her leg to come up to the height of the 
 first step of the bus. 
 
    
 
  Slightly embarrassed and with a quick smile to the bus driver, she reached 

  behind her to unzip her skirt a little, thinking that this would 
  give her enough slack to raise her leg She tried to take the step, 
  only20to discover that she couldn't. 
 
    
 
  So, a little more embarrassed, she once again reached behind her to

  unzip her skirt a little more, and for the second time attempted the 
  step. 
 
    
 
  Once again, much to her chagrin, she could not raise her leg.  With a 
  little smile to the driver, she again reached behind to unzip a little more

  and again was unable to take the 
  step. 
 
    
 
  About this time, a large Texan who was standing behind her picked her

  up easily by the waist and placed her gently on the step of the bus. 
 
    
 
  She went ballistic and turned to the would-be Samaritan and yelled,

  "How dare you touch my body! I don't even know who you are!" 
 
    
 
  The Texan smiled and drawled, "Well, ma'am, normally I would agree 
  with you, but after you unzipped my fly three times, I kinda figured we was 
  friends."
