The ONLY thing that comes to mind... is Queen's song "Under Pressure"

"Pressure pushing down on me (the parrot - in this instance)
Pressing down on you no man ask for (I'll presume the man let the parrot sit there - for now)
Under pressure - that burns building down (say no more! parrots and flammables NEVER mix!)
Splits a family in two (the parrot is like a child that never grows up)
Puts people on the streets (Purina Parrot Chow - like all consumables - must be going up in price)
It's the terror of knowing (isn’t THAT the truth - just knowing - parrot or naught!)
What this world is about (if Thomas Aquinas couldn't nail this concept down, then...forget about it!)
Watching some good friends (does a parrot-carrying person have such acquaintances...?)
Screaming let me out (those friends are tired of caring for and cleaning up after the parrot, following those too frequent trips to... Europe and/or Wal-Mart... I think...)

For the record, I think I need help in that I'm becoming wickedly tangential (bordering on abstract) in thought...

Some background...

* birds have feathers, which are modified scales
* birds have scales on their feet
* birds and reptiles both lay eggs
* both have similar soft anatomy (musculature system, brain, heart, and other organs)
* birds and reptiles also show some skeletal similarities
But, here's the thing... a parrot poops about every 15 minutes, every day. An adult boa only eats every 3-4 weeks. And parrots are loud, boas, not so much. So, I'm thinking the boa host is calmer and cleaner, probably more pleasant to be around.

BTW, my blog's alive now.

One time I saw a lady w/ a cat on her head. The cat was whistling.

I knew a guy who had a possum on his shoulder. They are quiet and still. Excellent answer Hasan! The only one that actually addressed the question, and quite aptly, I might add.

i'd be worried about poo

Is it a Norwegian Blue?

etr - was the possum guy in Seattle? I met a possum-shoulder guy in Seattle!
