While looking something up on Wikipedia the other day, I found an interesting website called 99 Bottles of Beer. On this website are a large number of implementations of a program/subroutine/etc. to write out the lyrics to this song, in just about every known computing language. Some of the implementations are compact, some not-so-compact. Some are serious, some are less serious (as in the case of C#, where the submitter creates a Class named Binge...). However, reviewing the various implementations does give you a way to compare some of the fundamental features of various different languages.
