“I made love for an hour and fifteen minutes. We turned the clocks ahead”

American comedian Garry Shandling (1949-2016) told a joke on a comedy special in 1989:
 
’‘I made love for an hour and 15 minutes. Well, it was on the day you push the clocks ahead.”
 
The sex joke (clocks are set ahead for Daylight Savings Time on the second Sunday in March) has been frequently cited.

25 January 1989, New York (NY) Times, “Review/Television; A Comedy Special Without the Bile” by John O’Connor, pg. C22:
There is something different about a comedy special currently on the schedule of Showtime, the pay-cable service. ‘‘The Comedy and Magic Club’s 10th Anniversary Special’’ is downright affable.
(...)
After Paul Kozak does a number of positively dazzling magic tricks with a decidedly loony glint in his eye, Mr. Shandling comes on, looking as pained and dubious as ever, to assure the audience that ‘‘the club is always decorated this nicely.’’ Proudly announcing that ‘‘I made love for an hour and 15 minutes,’’ he sheepishly adds: ‘‘Well, it was on the day you push the clocks ahead.’‘
