MissourA is a state in the US, wich is famous for its large population of "hook-people". The term "hook-people" describes a group of individuals, who have a hook instead of an arm. (you know...like pirates)
-Hey Johnnie! Where are you going with that hook?
-Oh, I'm just going to Missoura.
(However, in very rare cases, "Missoura" could simply be a dialect-form for the name "Missouri".)
