I had a lot of fun last week working with @Wendy Walker and @Abide on "What's In Your Pocket?". Let's do it again sometime, guys!
Speaking of fun, today is Halloween and we're expecting all sorts of ghouls and goblins to pay us a visit later tonight. Coincidentally, today also marks the 25th anniversary of our moving into our house. I can still remember the awkwardness back then when some trick-or-treaters showed up while we were carrying in boxes. For some strange reason they weren't interested in our music CDs or silverware. Talk about "tricky treaty" negotiations, eh @whimsy?!

The meta answer is a familiar six-letter Halloween figure.
