A friend of mine came up with a fun quiz in the pub on Saturday. As originally stated: how many professional sports teams have a name that does NOT end in the letter S? (i.e. no CanuckS, OilerS, PatriotS, DolphinS etc).
After I started to list Newcastle United, Manchester United, Liverpool, Chelsea, and showed no signs of stopping, the quiz was restricted to North American teams only.
After I started to list the LA Galaxy, Columbus Crew and New England Revolution, MLS teams were also excluded as being atypical of North American naming conventions.
We came up with eight, across the NHL, NBA and whatever initials you give your baseball league - not bad considering that none of us watch any basketball or baseball! A brief scan of Wikipedia indicates that we missed at least one... can you do any better?
