There's one I like that has a main "hook" line (repeated refrain line) "A ... wouldn't do me any harm." [I've heard such verses as "A pint of good ale wouldn't do me any harm," "A night with a lass wouldn't ...", etc.] You can insert whatever it is that wouldn't do you any harm. I couldn't find this in the forum or DT, and I don't know the name.

I also like Haul Away, Joe; Banks of Sicily; New York Girls; Ridin' On A Donkey; and several of the ones mentioned above.
