Update

A fly has been zooming around the living-room, periodically landing on Andrew’s newly-shaven head. He has asked me for the can of compressed air (meant for dusting, but he likes to use it as a ‘freeze ray’ on bugs).

I said as I handed it over: “I’m keen to see what happens when you try.”

A minute ago he fired it at the fly, which was not on his head at the time— probably just as well, as the plastic tube flew off the can and shot across the room.

I would like to point out that this is Andrew in his normal mental state.
