Thanksgiving Travel ~ 行きはよいよい 帰りは怖い

"Going is easy, returning is scary" is the lyrics I always think of when I go on a long distance trip. There are several urban legends around this song, named Toryanse. It is an old children's song in Japan. Nobody knows why, but it says something scary happens in your return trip, usually interpreted as a car accident. The music was often used with the traffic signals, probably warning people to be careful so something scary won't happen to them. The English translation is on wiki.
