Please read the rules in the sidebar before posting, and remember to always include a source for your fact.

Learn interesting facts about a variety of topics!

 

☰ Main Rules:
  • All site-wide rules apply, and we ask that you follow reddiquette.
  • Submit a topic using the format "TMAF about [topic]". Topics can cover nearly anything, e.g. animals, history, technology, and so on! Mark your thread "nsfw" (not safe for work) if appropriate.
  • Avoid re-submitting recent topics, by using the search function first.
  • Post your fact as a top-level comment. Please link to a reliable source or reference an offline source if possible. This verifies the fact, and also allows people to read more about it!
  • All top-level comments should be serious facts, i.e. no obvious/joke facts or non-fact (e.g. personal opinion) content.
  • Only include one fact per comment, so people can upvote and comment on the specific facts they're interested in.
  • Feel free to post as many facts as you want, even if you created the thread!

For our more detailed rules, please see the wiki. Have fun!

TMAF about the card game UNO

I’ll go first.

Not many people know this, but you are only legally allowed to play a Wild Draw Four if you do not have any cards in your hand that match the colour of the card on top of the discard pile.

If you have reason to suspect that the player before you played a Wild Draw Four illegally, you may challenge the play and that player must privately show you their hand. If you are correct in that they played the card illegally they must draw the four cards instead. But if you are incorrect you draw the four cards plus two penalty cards for a total of six.

TMAF about the history of same-sex marriage legalization in Italy

**Without this becoming a right-wing conservative cesspool of judgement and prejudice, please.

Bonus points if you are able to share information as a queer person in/from Italy.

This blows my mind that it hasn't been legalized. It also blows my mind that Padua is removing gay mom's from birth certificates to "protect the children". As someone from the States this sounds all too familiar.

Also.. per favore, share in English if possible. (If not possible I can translate the message online, but I want to have the most accurate translation and information possible).
