Last night I dreamt about three giant woodpeckers living on top of a grand piano. One of them had a clump of spring onions which it kept rubbing itself in, and another was playing a small cello.
This worried me. That is until lunchtime when Paul did his impression of "D infinity H" symmetry, before correcting himself to state he was infact "C infinity V". Linear but without a horizontal mirror plane. He ended the conversation with this gem:
"If you were going to photo-ionise me, what would you get?"
My dreams seem somewhat saner by comparison.
