As my grandpa used to say "The pussy is always good at Olive Garden"
Was he making this comment in reference to the women who work at Olive Garden?
I think it's only fair for males to make a joke about their own body parts, similarly for females about theirs
Comments like that could hurt others' feelings. You wouldn't want to hear a group of women talking about your body parts, right?
People need to get over it, it's just a joke.
Making derogatory remarks about females in this way is pretty low for your grandpa. Hopefully he does not often talk about females in this way, especially to his grandson.
