ELI5: Why do decks have two joker cards even though they're usually removed whenever playing a game? And why two when everything other card has four types?

Remember that cards are printed in large sheets and then cut.  If you want to make just 52 cards, your closest option to making them square is 4x13.  With 54 cards, you can print a 6x9 sheet which has much more manageable dimensions.  Many decks these days are printed on 7x8 sheets giving you 56 cards in the pack.
