One of my several arcane pleasures is building my own collection of limericks.
There is a paucity of limericks containing metalworking terms and/or job names like welder or machinist.
The words "tool" and "screw" appear in almost every third limerick, but the closest I've seen to anything having to do with mechanical or metalworking thewes are a couple of limericks related to the handedness of the participant's genitalia. i.e.:
A distorted young fellow named Fred Had a tool with a right-threaded head. He found, having hunted, A girl similarly-cunted, But alas! - with a left-handed thread.
Limerick offerings will be appreciated.
