The Stirling Prize for softball

David Attenborough: "In the warm weather they flock to open green spaces, seeking others of their kind, swarming across the grass in circular formations. This display is confined exclusively to the summer months and few of those who share their environment are even aware of its existence. They are architects... playing softball."

Yes, I found out last night that every Wednesday in the summer most of London's architects all go and play softball in Regents Park and follow it up by swamping the pubs of Camden. Apparently there were about 500 of them yesterday. The pictures in my head suddenly became all BBC nature documentary: wildebeest storming over the savanah; shoals of krill massing in the Antarctic; reindeer wheeling on the tundra, but all clad in serious designer glasses.*

Really, I mean who knew? You could probably halt half the building in the south east and seriously damage Nicole Farhi's British profit margins with a well-timed explosion.

*("So," I said to my informer, otherwise known as my flatmate. "How high was the poncey glasses count? Sorry to stereotype and everything..."
"Pretty low actually," he said. "I mean we were playing softball, people put their contacts in.")
