That is ‘unless’ the boat in question is not afloat
In which case it’s best not to anyway.
Never say ‘pig’ in a boat neither.
For both of these animals are said to be unlucky to be mentioned when afloat,
In a boat.
If thou shouldst be travelling with either of the aforementioned animals quoted above
Please refer to them as ‘bunny’ and ‘wiggy’
And no harm shall come to the floating craft
That you are upon.
‘Sheep’ is possibly also thought to be unlucky to converse about on a boat,
And a ‘cow’ is probably worse.
I have heard no mention of any problems with camels or giraffes;
But, they, too, would (in all likelihood)
Do the vessel of your sailing
So, to recap,
Best not to talk or comment upon any livestock
You are in dry dock.
