Just had one of those...
..."wait, what?" moments, when chappie on Dara's Science Club was talking about the 3D Printer and how you need a CAD file, and I thought, "hang on, wasn't that the monk played by Derek Jacobi..?"
I mean, I know what he actually said, but even so.
Although Sarah assures me that Cadfael's name is pronounced "Cad-fail." Typical Sarah, taking all the fun out of life... :-)
