[spoiler]Monday's quote:
Ep #891 (1969) - Philip - 'Surely whoever gave it to you MUST have told you.'
From "Robservations 4/14/03 - 890-891 - The Box Goes Whoosh; the Chosen Ones"
Philip can't guess what country it's from. Megan asks Barn if he knows where it's from, but he says he knows little about it--it was given to him. Surely whoever gave it to you must have told you, says Philip, but Barn says noHe's never looked inside, and asks them if they think that strange. Megan smiles and says they're very curious people. Philip asks if he'd consider selling it, but Megan tells her hubby they could never afford it. Barnabas doesn't want it in a shop, but they assure him they would never do that with it. He tells them he can see they are true collectors, and that they will discuss it another time.

The Robservations references the quote perfectly...
And this is the third quote from this ep. The first (Megan - 'It MUST be incredibly old') was back on April 9th of 2020, and the second (Philip - 'But you MUST let us pay you something for it') was back on March 18th of 2021.
