“Deck the halls with matzo balls”

“Deck the halls with matzo balls” is a parody on the “Deck the halls with boughs of holly” winter carol. The matzo ball joke has been printed on many images.
 
“Deck them halls with matso balls” was printed on Christmas cards in 1956.
 
       
Wikipedia: Deck the Halls
“Deck the Halls” or “Deck the Hall” (which is the original version of the lyrics) is a traditional Christmas, yuletide, and New Years’ carol. The melody is Welsh dating back to the sixteenth century, and belongs to a winter carol, “Nos Galan”, while the English lyrics, written by the Scottish musician Thomas Oliphant, date to 1862.
             
Wikipedia: Matzah ball
Matzah balls (Yiddish: קניידלעך‎ kneydlekh pl., singular קניידל kneydl; with numerous other transliterations) or matzo balls are Ashkenazi Jewish soup dumplings made from a mixture of matzah meal, eggs, water, and a fat, such as oil, margarine, or chicken fat. Matzah balls are traditionally served in chicken soup and are a staple food on the Jewish holiday of Passover.

One such card became the target for a bit of over-zealous police action in December, 1957. Washington, D. C., police closed up a stationery shop for selling a Christmas card featuring a woman holding up a string of tinseled balls, and the legend: “Deck them halls with Matzoh balls.” Police officials complained that the card was a “satire on the Holy Holiday.”

Her invitation had said: “Deck the halls with matzah balls,” but with luminarias lighting the path directly to the margaritas, the parody soon changed to “Deck the halls with hot tamales.”
