Givney must show up for work every day, knowing full well he's going to suffer a severe head injury eventually. But there's always something that distracts him, and keeps him from what ought to be Job One: getting rid of Jerry and his Violently Ordinary Rejoinders. For example:

Now then. If this happened to you on a regular basis - and trust me, it happened to Givney about six times a week - you'd shove your desk against the wall. The first time you flew from your chair and got your head wedged between wall and desk, you'd make sure it didn't happen again. But of course, it will happen again, unless you nail your shoes to the floor, fire Jerry, or nail Jerry to the tracks outside. Note Givney's trajectory - straight up and over. Yet his chair barely moves. Previous flip-takes have snapped the chair off its base; this time it just sits there, suggesting that Givney is somehow lifted by a force, rather than pushed by one.
