Today I was thought, that very few people know that MIT was designed this for us few decades ago!

1. foo
2. bar
3. baz
4. qux
5. quux
6. corge
7. grault
8. garply
9. waldo
10. fred
11. plugh
12. xyzzy
13. thud

Interesting what is next after thud ?

All these naming variables was described in RFC 3092. It is pretty funny to read it.
