While playing with the Solaris OS and reading through some of the included programs I came across /bin/true. For those not familiar with a *NIX system, this simply does nothing and returns sucessfully. Realizing that this was a shell script and not a binary executable, I decided to see how it was implemented.
bash-2.05$ cat /bin/true

I am not sure which is worse, that this is copyrighted, or that this is version 1.6. It really makes me wonder what the version history looks like.
