Skunks!

I have got a little skunk

My skunk is very dumb, my skunk does everything I want

My skunk is quite ambitious and on top of that so vicious

My skunk knows wrong from right, like a baby it sleeps at night

My skunk always gets the job done, its skills are second to none

And when things start getting smelly, only then my skunk is really happy

I know skunks are useful although not exactly truthful

And on their way to glory skunks tend to end up gory
