The title of the episode is a reference to the poem "Paul Revere's Ride" by Longfellow which commemorates the actions of American patriot Paul Revere. Referring to the signaling system to be used if the British were sighted, the verse runs:
He said to his friend, "If the British march By land or sea from the town to-night, Hang a lantern aloft in the belfry arch Of the North Church tower as a signal light,-- One if by land, and two if by sea"
The scene after Peter and his friends try to find a new bar involves Peter, Cleveland, Joe, and Quagmire standing beside a fence drinking tins of beer and only saying “Yep” repetitively. The scene is a reference to King of the Hill.
Cleveland’s line “Don’t tread on me,” spoken as they enter the British pub and try to reclaim it, is a reference to the First Navy Jack ensign, which featured thirteen horizontal red lines with a rattlesnake in the foreground.
Stewie’s attempts to teach Eliza to speak properly is a spoof of Eliza Doolittle, originally from the George Bernard Shaw play Pygmalion which inspired the musical My Fair Lady.
The scene in which Peter and his friends sneak on a British ship and pour beer overboard is a parody of the 1773 Boston Tea Party, in which the Sons of Liberty did the same with "bricks" of British tea.
Peter and the gang’s arrival in jail parodies a scene in the 1994 film The Shawshank Redemption. Peter’s method of carving an escape tunnel through the cell wall, seen later in the episode, mirrors the protagonist’s escape in that film.
When the guys enter the Clam's Head in Revolutionary War garb, they resemble the painting "Spirit of '76" by Archibald Willard.
