They make great slingshot ammunition. When I was a little kid, once I collected a Quaker Oats (cardboard) canister full and hid them under my bed. In a few days I started finding little white worms on my bed. I guess I was pretty nature savvy even back then, because it didn't take me long to figure out where they were coming from... inside the acorns. Each infected nut had an exit hole, and the buggers had eaten a hole in the cardboard at the bottom of the canister to get out, and I found a lot more on the floor. (Of course, back then no one had wall to wall carpeting in their bedrooms - thank goodness!)
