Every Monday at work, I send out an e-mail with a list attached of materials that arrived and were processed in the past week, so that the scientists can decide if there's anything germane to their interests. I always put a meme or comic in the body of the e-mail, more for my amusement than anything else, but quite a few people seem to enjoy it.
As you can imagine, in a natural history museum, this one was a big hit.
Have a good one! :-)
