Card: Pumpkins around the world:
Graseska – Netherlands
Kuebis – Germany
Tikba – Russia
Pumpa – Sweden
Calabaza – Spain

Card: Pumpkins were so common in early America that Boston's port was known as Pumpkinshire.

Card: Americans consume around 50 million pumpkin pies yearly, most between November and December.

Alton: You're in luck America, because today patriotic redemption comes on a plate – a pie plate. That's right – pumpkin pie, the most American of desserts.

(Discussing true American desserts.)
Thomas Jefferson: Wouldn't that be apple pie?
Alton: No! The apple originated in Khazakstan, don't ya know.

Alton: Pumpkin purée is tasty and versatile stuff, and since it's stupid simple to fabricate and it freezes well, there's no excuse not to keep it on hand at all times.

(Effects Guy suddenly hacks Alton's pumpkin to pieces with a large cleaver.)
Alton: I was going to eat that.

Alton: I guess you would fill that full of...
Effects Guy: Yeah! Red paint and squid meat!
Alton: Yeah, thank you. Good night to Effects Guy, thank you very, very much. Off you go!

Alton: Embrace your own home-made pumpkin pies, free and clear of any canned products which are obviously a plot by the French!
Jefferson: I like the French!
Alton: There's nothing wrong with the French. They did invent cooking, and fire and some other useful things. But this is America!

Alton cites several alternate uses for pumpkins since refrigeration made their shelf lives less relevant. One is as headwear for a horseman. He's referring to the Headless Horseman from Washington Irving's tale entitled The Legend of Sleepy Hollow. In the tale, the Horseman was once a Hessian soldier, part of the mercenaries hired to suppress the American Revolution. His head removed by a cannonball, he died instantly and his ghost roams the roads near Sleepy Hollow. An encounter with him proved fatal for Ichabod Crane, the central character of the story, who was discovered with a shattered pumpkin near him. Whether the pumpkin was a stand-in for the ghost's missing head, or used by a living hoaxer to simulate a detached head is left unclear. Before Irving used the character, headless riders appeared in European folklore going back centuries.

The pumpkin coach, another of Alton's suggested uses, appears in the fairy tale Cinderella. This tale has existed for centuries; a modern version of it features a much put-upon woman, Cinderella, who wishes to attend a dance but whose evil relatives will not permit her to do so. Appealing for help she draws the attention of a magical figure, her Fairy Godmother, who among other gifts transforms a pumpkin into a carriage and mice into horses. But, the fairy reminds the girl, this magic ends at midnight...

Peter Peter Pumpkin Eater is the name of a nursery rhyme about a man who had trouble keeping wives, until he hit upon the idea of keeping them in a (presumably) room-sized pumpkin.

The Lady of the Refrigerator, who dispenses nutritional wisdom from inside a pumpkin (she goes wherever the nutrition is, usually the refrigerator but this time not), is a character who appears from time to time, and is likely based on the Lady of the Lake, a character (or several characters, depending on the version) from the legends surrounding King Arthur, a legendary monach from around the sixth century who defended Britain. In some versions of the tale, the Lady traps Merlin and usurps his place as Arthur's adviser.

Alton notes that the use of the pumpkin to create a jack 'o lantern is “another show”. He's probably referring to his previous shows on Halloween treats: season seven's Tricks for Treats and All Hallows Eats, from earlier in this seasons.

Other applications for pumpkin purée are the subject of “another show”, one we likely will not see, given that this is the last season of Good Eats.
