When something seems familiar to you but you don’t remember it clearly you can say that it rings a bell. Imagine that someone asks you if you’ve ever heard of a pirate called Pugwash, the name sounds familiar to you but you can’t remember who he is so you say, “Pugwash, that rings a bell!”

I’ve never met Professor WB Rowe but the name rings a bell! La Inglesa, that rings a bell; doesn’t she write the blog English Telephone Classes?
