Skeeters.

There is a man at the end of the street my apartment is on who sits on his balcony every night doing what looks like newspaper word puzzles of some kind. He occasionally puts his paper down to pick up and swing what looks and sounds like an electrified tennis racquet made for killing mosquitoes. It looks like a lot of fun.

Also, the German sitting at a computer across the room is Wiki-ing Tyrannosaurus Rex.
