Dumb beetle.
So...tonight I thought the vermin were back. I heard a rustling sound and got up to investigate and after listening carefully discovered the noise was coming from a box of crackers on top of the cupboard.I grabbed the box and shone a light in expecting to see a mouse but found it was a Christmas Beetle. They are such clumsy, uncoordinated insects that it is a wonder that evolution hasn't just done away with their wings. If they could talk all you would hear would be "Oohs" and "Aaagghhs" and little, squeaky swear words as they crash into things. The one I found was blundering about the bottom of the cracker box wondering how to get out. It appeared to have forgotten it had wings.
