Edam cheese is the subject of a classic joke:
“What type of cheese is made backwards?”
The joke has been cited in print since at least 1939.
Wikipedia: Edam cheese
Edam (Dutch: Edammer, [ˈeɪ̯.ˌdɑ.mər]) is a semi-hard cheese that originated in the Netherlands, and is named after the town of Edam in the province of North Holland. Edam is traditionally sold in spheres with a pale yellow interior and a coat of red paraffin wax. Edam ages and travels well, and does not spoil; it only hardens. These qualities (among others) made it the world’s most popular cheese between the 14th and 18th centuries, both at sea and in remote colonies. A major producer of Edam is the FrieslandCampina company in Marum, The Netherlands. In the U.S., the May-bud brand is sold by the Churny Company, a subsidiary of Kraft Foods.

The sudden substitution of a mention for a use is the basis of much children’s humor ("What cheese is made backwards?” Answer: “Edam"); not all such humor is childish, as in the White Knight’s confusing but careful distinctions between his song, the name of the song, what the name is called, and what the song is called.
