You cannot call BS on someone after the next player has put a card down. If they're wrong, they have to take the pile.

Call bullsh*t of course! If someone does so, and they call your bluff you have to take all the cards from the centre pile.

However this will open a window for any player to. If someone puts an 8 down you can just slip your ace on top and call it a 9. Here's the fun part: You don't have to tell the truth. The next person has to place a card facedown on top of the previous player, now the catch is it has to be either one higher, or one lower than whatever the previous person played (so a 4 of something or 2 of something), if it's a king/ace it just rolls over. The first person to play puts their card face down in the centre and states what it is (eg 3 of clubs). Here's how it works: You get a normal deck, take out the jokers and then hand out the cards until there are none left (if there are leftovers just pop em face down in the middle). It probably has a proper name along and rich cultural history but screw it. My friends and I have this card game we play.
