This thread reminds me of that one movie . . . . .
GRUMPY OLD MEN
(1993 IMDB A lifelong feud between two neighbors since childhood, only gets worse when a new female neighbor moves across the street. John and Max are elderly men living next door to each other. They're continuously arguing and insulting each other, and have been this way for over 50 years.)
