“So what’s this place then?” Donna asks. “A junkyard?” There are unidentifiable objects everywhere she looks, scatted seemingly at random. Honestly, it’s a mess.
The Doctor splutters a bit. “Junkyard? This is the biggest art gallery in the universe! The collected works of the greatest artists of almost a thousand worlds are displayed here!”
Donna isn’t particularly impressed. “Art? You’re pulling my leg!”
“Why would I do that? You wanted culture, well here it is; every exhibit in this gallery is a work of genius. Most of them are worth a fortune!”
