A few days ago I found that if I left my screen-less window open for too long, a large mosquito would be able to find its way inside.
It startled me and I made ready to swat it, but realized, "this guy cant bite me." and thought.
Then did proclaimeth, "I pronounce you zippity, and also my pet. We shall share residence, which means you are free to buzz around and ram your head repeatedly against the ceiling till the end of your days, which is most likely to arrive within the next few days."
