Man: Well… I was about seventeen and some mates and me went to a party, and, er… we had quite a lot to drink… and then some of the fellows there … started handing … cheese around … and well just out of curiosity I tried a bit … and well that was that.

Interviewer: And what else did these fellows do?

Man: Well some of them started dressing up as mice a bit … and then when they’d got the costumes on they started … squeaking.

Oh, wait. Wrong source of squeaking. It’s winter here, so we’re talking about snow.

Update: I shoveled some squeaky white stuff this afternoon. Just as I finished, it started coming down heavy again. Prediction: 2″-4″, actual was about 6″.
