Superman HATES Supergirl
from Superman #14

Superman Family #195, June 1979, cover by Ross Andru and Dick Giordano
The title really should’ve been Superman Dysfunctional Family
Supergirl #7, October 1973, cover by Bob Oksner

There is literally no part of this comic panel that isn’t hilarious. Supergirl is being a bitch, Superman doesn’t understand women (but likes them), and Wonder Woman (despite being nominally from a place in Europe) seems to think that someone capable of flying back from there in a minute or so is shirking responsibility.
