Not to toot my own horn, but at work once, I nearly killed a very annoying coworker by making a joke.
 
Her name was Carla, and she was an idiot. Another woman who worked with us, a very conservative and proper lady named Patty, stood a chunky four feet tall and had a deep Nehw Yawwk accent. She was basically a prim, Brooklyn Oompa-Loopa.
 
During lunch, as a joke, I knelt down behind Patty's desk and began shouting vulgarities at everyone in her voice. 
 
Everybody laughed, including Patty, and the annoying idiot Carla got a big hunk of bread stuck in her windpipe. It took two people trying for a good thirty seconds to Heimlich it out.
 
At least five people came up later and said, "Better luck next time ..."
 
Joe, killer-diller
