The waspy lock-jaw way of speaking has been an endless source of humor for me and my old coworker when we had desks next to each other at the old boeings company. And then we would try to slip in cuss words like, "That's a terrible shituation, Christine." And then it would snowball into this endless, absurd list of cussing but not really:
Let's visit Massachushits.
Have you seen video of the Space Shittle.
Doing Shit-ups at the gym.
You'd better toss that in the shanitation can.
Finally, someone at the next cubicle had to tell us to "shut up."
