Out of office

An opportunity for the daring (like yours truly) to be waggish, and for the anal to clog up the word's inboxes buy mysteriously contriving an automatically generated out-of-office message that replicates itself like a fruit-fly and issues in triplicate however many emails you send to the same person.

We suspect that those who generate multiple out-of-office messages are the same sort of folk who have never discovered their “sent items” folder, and hence cc themselves onto every email message they send, so they don’t lose it.
