"It's a ticklish sort of job making a thing for a thing-ummy-bob,
Especially when you don't know what it's for.
But it's the girl that makes the thing that drills the hole that holds the ring
That makes the thing-ummy-bob that makes the engines roar.
And it's the girl that makes the thing that holds the oil that oils the ring
That makes the thing-ummy-bob that's going win the war.
It is 'n all."
"The Thing-ummy-Bob", a British song made popular by Gracie Fields[1]
"The Thing-ummy-Bob [That's Going To Win The War]" is a 1942 song, written by Barbara Gordon and Basil Thomas with music by David Heneker, which celebrates the female production-line workers of World War II making components for complex weapons to win the war.[1] Its chorus is
I'm the girl that makes the thing
That drills the hole that holds the ring
That drives the rod that turns the knob
That works the thing-ummy-bob
A thingumabob or thingummy is an extended form of the word thing which the Oxford English Dictionary records being used as far back as 1751.[2]
The song was popularized by performers Arthur Askey and Gracie Fields.[3]
