Bugger!

Great Aunt Annie reports;

"When I was about 14 I had the happy experience of watching a tallish van heading for a low overbridge.
With slow motion inevitability, the van came to a sudden stop as the top two feet crashed into the brickwork.
The driver leapt from his cab and ran around making despairing gestures, like a scene from an old silent movie.

I'm ashamed to say I thought it was hilarious and I cycled away chuckling to myself."
