I didn't think our group would be the only one to come up with that pun. :)We had a somewhat more standard way of dealing with our corn. We couldn't see the point of keeping the bank on the cog in the first place. Therefore, we kept it off-board next to the resource and skull supplies and the cog was only used to hold the turn-accumulated corn, just like you would in any other game.
This way, you avoid the fiddly balancing act of trying to put the corn on the teeth, the corn falling off during cog rotation or having the bank/accumulated corn getting mixed up if the board gets accidentally knocked.
