Talk:thinking cap

Also an actual cap, worn while smoking?
on Wikipedia says that this can also be called a thinking cap; is it true? Equinox ◑ 21:35, 8 May 2020 (UTC)
 * I wouldn't take much notice of that uncited stub on Wikipedia. That information was inserted by a single purpose account that did several other dubious things to the article at the same time.  It removed the only source and inserted an unsourced nationalistic claim over origin (which may or may not be true).  I'm inclined to revert that edit entirely.
 * The first verse of a poem in this book might suggest it.  Spinning Spark  12:32, 9 May 2020 (UTC)

THE SMOKING CAP The cap, dear Mrs —, the cap with neb most neat, A fit delightful, and design complete; A thinking-cap, to cover sleep and brains withal; Or smoking-cap, to swagger in the hall. In hours of dull retirement, when reflection reigns, Or warmer moment when the passion gains Supreme control, and moves the heart right far away, May your black cap forbid the mind to stray.
