#7 might that be from Prescription:murder? I guess this is said by one of the (female) guests in doctor Felming's house at the beginning of the episode when they're all playing a sort of "find out who I am impersonating" game.
Caroline Treynor in "Bye Bye Sky High," while doing the inventory of the house.
9. "They said I'd get into trouble."
Joanne Nichols in "How to Dial a Murder," talking about her parents' reaction to her moving into Eric Mason's house.
10. "My house is your house."
Besides Montoya (noted by Bob Branca), I think the nun said this in "Negative Reaction," just before she tried to find Columbo a new second-hand coat.
14. "You have got to make her grow up..."
Leslie Williams's friend, Pat, said this after Margaret slapped Leslie at her father's funeral. She also said she would turn her out without a dime.
Bonus: "I never noticed it before."
YM got one of these--the realtor in "Negative Reaction." The other person who says this is Joanne Nichols, when Columbo asks her what the hook in the ceiling in the kitchen is used for.
