I solved the current WESUN Puzzle with some Perl programming. Whee. And this time, I actually sent in an answer. Last week, I got the answer but didn't send it in, and then saw that they got only 150 correct responses.
This week's puzzle:
The word EFFERVESCENCE is unusual because E's are spaced out in it. It has 13 letters, and E's appear in positions 1-4-7-13. Now, think a familiar two-word phrase in 15 letters, in which the letter R appears in positions 1-4-8-12-15. These are the only R's that appear in them. What word is it?
