Weasel Woes

From Hanoi
I was given a gift,
A parcel which I'd never expect to receive...
'What is it?' aloud I wondered
'Open it' I was instructed

'It's coffee!'
Obviously, but of FINE quality!'
'Tell me the reason why?'
'Later, after you have a try!'

And so did I, with a sigh...

'Ever heard of the weasel;
- the crafty creature?'
'Yes, always;
- in kiddie literature'

'He goes from tree to tree,
selecting coffee beans of best quality,
but as smart as he can be,
never chews the seeds ever does he...'

'You and I both know,
the fate of any seed; if swallowed whole,
Physiology of the GI tract, dictates that...
What's not digested, comes out from the back!'

What I've ingested has been revealed,
And no, there wasn't a need for Lomotil!'

To my coffee-mate
I thank you once again
For the gift, and experience I've gained!
