Sir, don't eat that biscuit,
If you care to keep your life.
The consequence to risk it,
Could be sanguinary strife.

For in amongst the crumbs for good,
Are many more for bad.
To slowly poison healthy blood,
The rest is rather sad.

So think before you take a snack,
And ask 'what will this do?'
For soon there'll be no looking back,
The choice is up to you.
