“Give me a bell.”
Some people believe that this saying is a reference to the telephone’s alleged inventor, Alexander Graham Bell.
I’d say the more logical explanation is that when you dialed somebody’s number in the old days, the bell on their phone would ring, which is why we now say, “give me a ring” instead.
In either case, I’d be tempted to respond in the literal sense, just to be a pedantic asshole.
Another expression is, “Give me a tinkle.” I’ve no idea where that comes from but know that it means people want you to you to call them.
There used to be a sign in the school toilets: “If you sprinkle when you tinkle, always wipe the seat.”
