Ooh - my first QOTW pearoast
I have to drop this one in again from the other week's school days question. (http://www.b3ta.com/questions/schooldays/post360597)

As a child, I had literally no sense of danger at all. For example, we developed a fun game, which was to climb out and move from window to window (a good two storeys up) along a ledge about three inches wide. I got very good at this, and eventually did a run of about twelve windows, ending on a windowless alcove, where I chalked some large words.

Shortly afterwards everyone was called in for a little talk. I managed to miss it, so I understand it went something like this:
'It's come to our attention that some people have been climbing outside the windows. This has to stop... Where's Flatfrog?'
'Out on the window ledge'

Further window-related japes were to be had when I discovered that sitting outside the window with a gown over my head after dark, I was completely invisible. This particular prank came to an end when our teacher (wonderful man) came in and looked around.
'Where's that frog?'
Shrugs all round. Then he notices a disembodied head floating outside the window going 'Wooooooooo'
