The weirdest place to get a sliver.... TONGUE. This is possible, you don't even have to be eating a piece of wood. Don't try that unless you have to. The ones that hurt the most are, I think, metal or fiberglass. But wood and hay hurts just as much. Yes, you can get slivers from hay. That's how I found out the weirdest place. I have no clue at all his I managed to get a hay sliver on my tongue. It was extremely awkard to get out but it gave me the perfect excuse to stick my tongue out at my grandpa. He hates it. Oh and no. I wasn't eating the hay, I was helping unload some wagons.
