The original line was too rude for public consumption, so various substitutes were sung when carrying passengers or within earshot of land. That is why there are so many different endings to this chorus, only one of which is *ringtail warm*. Others are *I wonder if me clothes are out of pawn* & *Jenny get yer oatcakes done* Title varies somewhat too, as the original was a wild "whoop" sounding like *whip* or *whup* so sing what you prefer, so long as it's with gusto!!!
