Idiom: Rings a bell

Context:

"Here, do you remember David Bedlington from school."

Explanation: To seem familiar, or to make someone remember something.

Notes: Church bells used to be much more useful than they are today. In the days when ordinary people didn't have clocks or watches, they had to rely on the church bell ringing out to tell them when it was time to go to church or school. They therefore acted as a reminder.
