Some people just play too well together.

co-worker: "Did you say to alarm the building when I leave, or not to alarm the building?"
my boss: "If you are the last one to leave, you should alarm the building."
me to my boss: "See, I told you you were alarming."

my boss: "My network cable says it's disconnected."
me: "Do you want an expression of sympathy, or am I supposed to fix that?"

me: "Why is it, when it's yours, it's a cock, but when it's somebody else's, it's a dick?"
my boss: "I don't know, but I have contemplated this question at length."
