I was just looking at a brochure for our local YMCA, and right at the end it admonishes the reader that
100% attendance and participation are required for courses marked with an apteryx (*).I'm used to seeing it misspelled asterix (not to be confused with the indomitable Gaul), but this is a new one. Excuse me while I squint at that tiny star to see if it really does resemble a wingless bird with hairy feathers...
