Lexie's line about the Algonquin explained

When Lexie and Dodge are trading barbs at the bar (after Dodge walks in with a young girl), Lexie says to him, "How quiet it must be at the Algonquin with you here in Duluth." I think that is the funniest line in the movie and I laugh every time I watch it. However, it is a period reference and probably goes over most viewer's heads.

The Algonquin Hotel is located in Manhattan and opened in 1902. In 1919 the hotel became the site of the daily meetings of the Algonquin Round Table, a group of journalists, authors, publicists and actors who gathered to exchange witticisms over lunch. The group met almost daily for the better part of ten years.

By 1925, the Round Table was famous. What had started as a private group became a public amusement. The country-at-large was now attentive to their every word; people often came to watch them during lunch. The group was known to be literate and intelligent, and the members had a very sharp wit.

Lexie is insulting Dodge's intelligence and wit by implying that he is a member of The Round Table and without his amazingly brilliant dialogue the other members must be sitting around quietly without much to talk about. All tongue in cheek, of course ☺
