I once saw a businessman being chased by a giant ball of foam down the streets of Bath. That was funny. ^.^

(Bath contains some lovely fountains which are prime candidates for a bottle of washing-up liquid on a Saturday night.)

This businessman. He wasn't played by Patrick McGoohan, by any chance? :-)

I know! That's exactly what I thought!

I thought, "he wasn't called Mr. Lynn was he?" But probably more people have heard of the prisoner than read Dianna Wynne Jones. I was about to complain that I couldn't google for "mcgoohan giant ball of foam" successfully when it clicked for me :)
