Today I had to talk to my co-worker "Bob", so I walked over to Bob's
cubicle, knocked, and poked my head in. However, another co-worker (whose
cubicle this isn't) was sitting there at Bob's desk. In a fit of
brilliance, I said, "You're not Bob!"

It later occurred to me that we can draw upon this experience to introduce a
little surrealism into our workday. All we have to do is find someone who
is sitting at their own desk like usual, walk into their cube, and say
"You're not Bob!"
