What's In My Coffee?

What's in my coffee...
Eww, is it pee?
What's in my coffee...
What?! Snow from a ski?

It stinks... Having a bad day.
My coffee, bringing me dismay.
Uh, there's something HARD in my coffee...
An old, rotten, wooden key?!

What else is in my coffee, perhaps, something rare?
Umm... Oh gosh... It's someone's hair...
There is something very slim...
Uh, it likes to swim... (a slim fish)

It's rich... With... Protein?
Is it, even, clean?
The maker of the coffee, I need to discuss...
Meanwhile, I love Opuss!
