From the frightening to the just downright bizzare, you'll never believe the crazy things that passengers actually thought they were going to carry right onto an airplane! Luckily TSA caught them first!
A biology professor was on vacation when he came upon a dead harbor seal. So what did he do? He cut off the head to bring back to show his students. Unfortunately that isn't exactly illegal and his seal head was confiscated at the airport though he was allowed to board the plane home. I'm sure his students were devastated.
