Various stupid things you can do by using the shebang to select unconventional interpreters.

chronic-self-discovery

#!/usr/bin/env touch

This file just touches itself when you try to make it do anything. 

quine

#!/usr/bin/env cat

Prints its own contents when executed; ergo, it is always a quine. Could also be done with less/more/dog.

This one could be slightly useful in some situations (small documentation files and readmes?)

say-my-name

#!/usr/bin/env echo

This just prints its name whenever it's called. 

say-my-name-forever

#!/usr/bin/env yes

This just prints its name endlessly whenever it's called. 

suicidal

#!/usr/bin/env rm

This file deletes itself if you run it

In other words, it dies if you execute it
