Update: Wow! We have multiple winners today! First up is Tige from Blue Tige who gave us biters and daters (an interesting combination there...); next was Raging Mom from The Splatter Zone who contributed bestir, nebula, and stared; and rounding out the winners is Taleena from Sun Comprehending Glass with unbale and trades.

You all deserve a smartypants sticker! Thanks to Harvey, here you go!
