My good friend Adam Stewart, rest his soul, always used to sing a Gaelic version after he had knocked back a goodly amount of the water of life. And then swear the next day that he knew not one word of Gaelic! He then used to announce it as the 'Wet String song'.

Knock. Knock.
Who's there?
Wet string.
Wet string who?
Wet string home wi' a song in the air.

Sorry...
