Lloyd's of London is a strange institution. It's a 330 year old insurance market founded and headquartered in London. The unusual thing about it is that it will insure pretty much anything. Wikipedia has a list of unusual things that Lloyd's has insured:

• A comedy theatre group against the risk of a member of their audience dying of laughter
• Cricketer Merv Hughes' trademark walrus mustache while playing for Australia between 1985 and 1994
• Food critic and gourmet Egon Ronay's taste buds for £250,000
