Sometimes it's the really small things that crack you up.
Two cases in point:
A piece of spam in my gmail inbox addressed to "rotten coroner".
Our lunch menu in the cafeteria at work, which is posted on the intranet for us to check out. Every day there's a regular special, a healthy offering and a vegetarian dish. On Friday the vegetarian special was an open faced roast beef sandwich.
Maybe I'm just easily amused.
