This took place many years ago, but at the end of the year one of my co-workers was leaving. A bunch of people in his department gave little speeches about him and they were very nice.
The last guy didn't get along really well with him and ended his little speech with this: "__________, if my doctor told me I had a month to live, I'd want to spend that month working with you, because it would feel like it lasted forever."
A couple chuckles, but mostly awkward silence.
