After the agency was laid to rest in 2006, one of its founders, Axel Chaldecott, took it upon himself to set up a Wikipedia entry for the agency, so its achievements could live on in the digital world.
The site included information about the shop's best work, including the Blackcurrant Tango "St George" ad and the infamous Ronseal campaigns from the 90s.
All was well until an editor of Wikipedia, a Latino-Californian with a soft spot for Abba named Carlos, began to question the "notability" of the agency.
Despite protestations from the founders, Carlos felt HHCL was simply not distinguished enough to sit alongside the likes of Jamie Ginn, the 2006 winner of Miss Delaware, and struck it from the site.
