Some giddy prankster was recently arrested for scattering 200 beetle larvae on a train in Neyagawa, Osaka prefecture, and disrupting the daily rail schedule. When the police nabbed him, they found he had thousands of the squirmy little things in film cases. His excuse?
"(The worms) wiggle around and are so weird. I like seeing people surprised."
Here's some advice-- next time, try baking a cake or making delicious popcorn and serving it to the passengers. Or jumping out and screaming, "Boo!" Or simply saying something nice and complimentary to your seatmate.
Everyone likes to get compliments, right?
