“King of the one-liners” Henny Youngman (1906-1998) told many jokes about his wife, such as “Take my wife—please!” In 1981, Youngman said this about his wife’s cooking: “The only thing she can make for dinner is a reservation!”
 
The usual form of the joke involves a Jewish wife or, especially, a Jewish American Princess:
 
Q: What does a Jewish American Princess make for dinner?
A: Reservations!
 
The joke dates in print to at least 1981-1982 in both the “wife” and “Jewish American Princess” forms.
