Sitting together on a train were Pres. Obama, George W. Bush,
  a little old lady, and a good looking young blonde woman
  The train goes into a dark tunnel and a few seconds later
  There is the sound of a loud slap.
  When the train emerges from the tunnel,
  Obama has a bright red hand print on his cheek.

 No one speaks.

 The old lady thinks: Obama must have groped the
  Blonde in the dark, and she slapped him.

 The blonde woman thinks: Obama must have tried
  To grope me in the dark, but missed and fondled
  The old lady and she slapped him.

 Obama thinks: Bush must have groped the blonde in the dark.
  She tried to slap him but missed and got me instead.

 George Bush thinks: I can't wait for another tunnel,
  So I can slap the s$$$ out of Obama again!!
