I present to you, the coffee fandom.
In the late ’80s and then again in the ’90s, Taster’s Choice ran an extremely popular set of soap opera–style commercials, first in Britain and then in the U.S. The series explored the twists and turns of a relationship between actors Anthony Stewart Head (a.k.a. Giles from Buffy) and Sharon Maughan (Holby City) as it developed—over coffee… The series was so popular that it actually got a work of fanfiction written about it: a now-out-of-print romance titled Love Over Gold.
I ship these two so hard.
