This sounds close to Emil Sitka’s line “Hold hands, you lovebirds” in the Three Stooges short Brideless Groom. Are you sure you’re quoting correctly? Or is that actually a line from another film?
Emil Sitka was in a lot of Three Stooges shorts, and was almost Larry Fine’s replacement after his stroke. But he’s best remembered as the justice of the peace in that on Stooges short. Until the end of his life he was in demand to perform marriages for Three Stooges fans.
Notably, a clip of this short is featured in Pulp Fiction (1994), for which Sitka’s name even appears in the credits as “Hold Hands You Lovebirds.” Emil also utters the phrase in his cameo as a supermarket customer in the horror film Intruder (1989).
Later years
Sitka continued his acting career, more out of love for acting than the need for money, appearing in films as late as 1992. He was in demand at various Three Stooges conventions, and he had numerous requests from Three Stooges fans to appear at their wedding to say “Hold hands, you lovebirds!”
