Mr. Poo?

Over the city skyline this morning, I spotted the following vapour trail:

Turns out they weren't writing "poo" at all - but "pacific". What a shame.

For the brief moment wherein the possibility of scatalogical skywriting lingered, I was reminded of a Touchwood incident in the UK...
We were having brekkie with our hosts one morning when a plane flew over, trailing a sign. The text was backwards from our vantage point, and there was much discussion about what it said. The best suggestion by far was "Mr. Poo?!".

Then, as today, the fact was much less entertaining that the fiction.
