from Dan's Domain Hall of Shame site.

Yahoo also acquired EGroups, and now has its website at the logical subdomain groups.yahoo.com, but for some reason the email messages generated from it use the less logical yahoogroups.com in the return address. And, for yet another unneccessary extra domain, files in the Yahoo Groups file libraries are served from subdomains of yahoofs.com. (Just what are "Yahoofs" anyway... something that Yahorses have???)

http://domains.dan.info/hall/shame.html

However, if you type in yahoofs.com
this is what comes up.
