Well there are interesting, far reaching suggestions and then a historical perspective:
The riddle appeared in an 1847 edition of The Knickerbocker, a New York City monthly magazine: ‘There are ‘quips and quillets’ which seem actual conundrums, but yet are none. Of such is this: ‘Why does a chicken cross the street?[’] Are you ‘out of town?’ Do you ‘give it up?’ Well, then: ‘Because it wants to get on the other side!’ (Wiki)
But, I doubt anyone ever considered “to get to the seafood place”! Just saying…….
