Hi, guys. I'm looking to get into Android development (Xamarin) and to build some simple apps first.

What I have in mind is something trivia-like, with a hosted database (can't find any free & reliable public APIs).

Do you know of any free downloadable databases on the topics of:
- trivia
- humour
- entertainment

http://www.usabledatabases.com/ seemed promising, but it's not free (or I couldn't find any free DBs, as they don't have a price filter).

Thanks in advance!
