"It was so hot in New York that fat guys were making…

Television’s Late Show with David Letterman (1993-2015) was based in New York City, and there were many New York City jokes. David Letterman told this joke in July 1994:

“It was so hot in New York City today, fat guys were making their own gravy.”

14 July 1994, Toronto (ON) Star, “Club Crawl” by Lenny Stoute, pg. C12, col. 1:
Standup bass, drums and guitar create suggestive cityscapes for Love’s musings, getting the tiny crowd in total sync, even though it was so hot fat folk were simmering in their own gravy.

I throw up a softball, and nobody takes a swing! I always liked Carson/Letterman when they would do this. I’ll never forget Leterman’s “It’s so hot out there in Central Park, the fat guys are making their own gravy.”
