QuoteEdit
"Until Wikidata can give me a list of all movies shot in the 60s in Spain, in which a black female horse is stolen by a left-handed actor playing a Portuguese orphan, directed by a colorblind German who liked sailing, and written by a dog-owning women from Helsinki, we have more work to do." — Tobias1984 18:39, 7 December 2013 (UTC)
