You know you're probably a hitchhiker when...
- Your name's only pronoucable in an obscure, near-dead dialect
- You change that unpronouncable name to that of a late-1930s British car
- Your motto in life is "Don't Panic"
- You have a fish in your ear
- No matter where you are, you always have a towel
- Time travel is a regular thing for you
- Terminally depressed androids, interdimentional creatures, and homicidal robots, among other things, are nothing new
