I attended a meetup in Toronto last night for drawing & sketching, and the theme was Autumn Bingo: draw a fall scene, after which the organizers call out a series of things and you count how many of them you managed to put in your drawing.
I did not have enough time to pack mine full of *everything* and I only got 2 points 
(I had leaves and a squirrel, but I was missing apples, acorns, and a scarecrow)
