Wednesday : Words of the Week - episode 2

If you thought I would forget this, you fail to understand the depths of my compulsion. But, in recognition of jetlag and associated confusion, let's keep it brief.

Lazy Susan, Merry Andrew, Doubting Thomas, Bloody Mary, Jolly Roger, Black Jack, Spotted Dick. Let's cut it off there, shall we, and not open the door to the likes of willy nilly, peg leg, and charley horse. Well, OK, those three, but no more. Sadie Hawkins, you stay right where you are! This gives as our final list:

1. lazy susan
2. merry andrew
3. black jack
4. peg leg
5. charley horse
6. spotted dick
7. bloody mary
8. jolly roger
9. doubting thomas
10. willy nilly

By my count, only two of these terms always refer to an actual person. Which two? And what do the other terms mean?

Feel free to add your own suggestions.
