Why Sentence Structure Is So Important...

 The boss had to fire somebody, and he narrowed it down to one of two people,
Mary or Jack.. It was an impossible decision because they were both super
workers. Rather than flip a coin, he decided he would fire the first one who
used the water cooler the next morning.
 Mary came in the next morning with a horrible hangover after partying
all night. She went to the cooler to take an aspirin. The boss approached her
and said: Mary, Ive never done this before but I either have to lay you
or Jack off  
 Could you jack off? she says......I feel like sh*t.
