I saw a buttefly flutter by
and saw a catterpiller wave his pillock at 'er?

The other interesting thing is that Martin said to his man seems to be a servant talking to or about his master - Looking after him when he is drunk. It later became popular usage to refer to a servant as 'my man' but I believe in this case the 'man' is indeed the master.

'Fu' being drunk? As in 'full'? I do find it very unlikely. Fool and Fou (as in French for mad) yes, I will have that. But I find the Scottish dialect connection very unlikely. I know lots of Scots and I have never heard one refer to being drunk as being 'fu'. Pissed, Rat-arsed, Shit-faced - Yes. Fu - No.
