“A professor is one who talks in someone else’s sleep”

“A professor is one who talks in someone else’s sleep” is a jocular quotation that has been attributed to the poet W. H. Auden (1907-1973) since at least 1940. The quotation has appeared in many collections of quotations about college.
 
Another saying about sleeping through lectures is “Now I sit me down to sleep; the speaker’s dull, the subject deep.” A backronym of “class” is “Come Late And Start Sleeping.”
 
   
Wikipedia: W. H. Auden
Wystan Hugh Auden ( /ˈwɪstən ˈhjuː ˈɔːdən/; 21 February 1907 – 29 September 1973), who published as W. H. Auden, was an Anglo-American poet, born in England, later an American citizen, regarded by many critics as one of the greatest writers of the 20th century. His work is noted for its stylistic and technical achievements, its engagement with moral and political issues, and its variety of tone, form and content. The central themes of his poetry are love, politics and citizenship, religion and morals, and the relationship between unique human beings and the anonymous, impersonal world of nature.
