What is your favorite Downton Abbey line?: “What is a weekend?” the Dowager Countess’ reply to cousin Matthew after he talked about his “weekend” plans?

Or how about Violet’s retort to Isobel about the latter’s generosity: “I wonder your halo doesn’t grow heavy. It must be like wearing a tiara round the clock.”

You can whip out some of the best comebacks from the show by downloading the Downtonisms app. It’s available for both iPhone and Android phones.

It includes tons of sayings from the main characters. Click on the character and you can scroll through their most memorable lines. You can also listen to them speak the line by hitting the audio button, take a “Whose Line Is it Anyway” type quiz, save your favorite lines and then share them with your friends.

One of the fun aspects of this app is rediscovering clever character lines.

Here are some memorable bon mots from Lady Mary:
“At least I’m not fishing with no bait.”
“Haven’t you heard? I don’t have a heart. Everyone knows that.”

And here are some of the hilarious sayings of Mrs. Patmore:
“I said you could go for a drink of water, not a trip up the Nile.”
“Oh dear. Have you swallowed a dictionary?”
“Do I look like a frolicker?”

If the app has pitfalls it is that cousin Matthew, Mr. Bates and Anna are not included it. But it’s a hoot all the same.
