This isn't really a laugh line, but I was disappointed that it got zero reception.
At my office, my co-worker, good friend, gets boxes and boxes of sample goods that we might potentially sell in our stores. He ran out of space in his cube and started keeping the boxes in my cube, which is fine because it's random fun stuff like christmas cookies and nerf balls and whatnot. It became a running joke between us as more and more stuff started arriving and taking up more of my cube. One day he gets an unusally large cluster of new boxes, and he starts stacking them at the entrance of my cube as a joke, acting as if he was completely sealing me in. I work in an office of bright, young, very well-educated people, so I say, loud enough for a couple people who were watching the scene to hear, "What is this, the cask of Amontillado?"
zoooooooooooooooooom. Not one of my Ivy-league coworkers got the reference.
