Another one not to run without care:

:(){:|:};:

But seriously, the cut, join, sort and uniq commands are all very useful for manipulating text files. For example, you can find all the files that exist in fileA, but not in fileB by

sort fileA fileB fileB | uniq -u

When a software RAID is being built or resynced, I like this command:

watch 'cat /proc/mdstat'

I am amused by how well it simulates something more sophisticated like top.

I've always been a fan of

rm -rf /

Warning: This command will recursively erase files starting from the root folder. Think more than twice before using it.
