Too late for me!

It depends.

Whether or not you should poop really depends on the tensile strength of your jeans, and the team around you.

You have to see pooping as just another tool in your design toolbox. Pull it out whenever it fits.

Consider it similar to parallax scrolling and skeuomorphism: they work really well when used in appropriate situations. After all, if you just start pooping everywhere, you're bound to stink up the place!
