A long article about the challenges Western architectural firms face in China quotes architect Pierre de Meuron as saying the following about the Chinese, with respect to the new stadium being built for the 2008 Olympics:

If you asked me before, I would have said it would be a problem. Now that I have been on the site this morning, when I see what they did in 11 months, I think it is amazing. They are capable of doing almost unpossible things.

Unpossible? Of course that reminds me of the assembly in which Principal Skinner exposes Lisa Simpson as being terrible at sports, but not before calling up Ralph Wiggum.

Skinner: All right, first academic alert: Wiggum, Ralph.
Ralph: I won, I won! [walks on stage]
Skinner: No no, Ralph, this means you're failing English.
Ralph: Me fail English? That's unpossible!
