Watching Columbo, S02E04 Dagger of the Mind and this exchange takes place between Columbo and a Detective. They are in a gentleman's club, leather furniture, bookcases of old books, butler, etc.
Detective: Would you, uh, care to sit here?
Columbo: When you said "club," I thought you meant a country club or a health club.
Detective: Mm. Bit stuffy, I'm afraid. Hasn't changed since Father's day.
Columbo: My father was an Elk once, till my mother stopped him.
It is quite hard to hear what Columbo is saying but it sounds like he's saying "My father was an Elk once".
I don't know what this might mean though, in the context.
