"Who's for Dinner" is the first segment of the twelfth episode of Rocko's Modern Life. It is considered one of creator Joe Murray's personal favorite episodes because he enjoyed the premise and the development of the concept of adoption.
Rocko, who is unaware of Heffer's family life, is invited over to dinner at Heffer's house.
Chronologically and in production order, this episode is supposed to be the first appearance of Heffer's family. However, due to the anachronic airing order, this episode ended up airing after "Bedfellows", which Heffer's folks also appear in.
