I found out yesterday that eating too many jelly beans can cause your tongue to feel raw. I also found out that it is possible to pull a muscle in your tounge after yawning in a weird way. That sucked. It hurt to talk or swallow for a few hours. I've actually pulled a muscle in my touge before, after I formed my tongue into a 'W' shape and held it like that for too long. Really, though, it really hurts to pull a tongue muscle, and it extra-sucks because you can't do anything about it but wait out the pain.
