In page Monty Python and the Holy Grail:
"On the special edition DVD, the studio logos, opening credits and a brief portion of the opening scene of 1961 British film Dentist on the Job is added to the start of the film.

A "slide" then appears urging the audience to wait one moment please while the operator changes reels.[citation needed][8]
