Can I call a discarded Joker in American Mahjong?

No. A discarded Joker is dead the moment it lands. Nobody may pick it up, call it for an exposure, call it for Mahjong or trade anything for it, not even a player who needs it as the winning tile.

Down is down, and a Joker is down for good

Every other discard has a brief life. It lands, the table has a moment to call it, and then the window closes. A Joker skips that moment entirely. The instant it reaches the table it is dead, and it stays dead for the rest of the hand. There is no calling window to miss, because there was never one to begin with.

That holds for every purpose. You cannot call it to complete a pung or a kong. You cannot call it for Mahjong, even if it is the only tile standing between you and the win. You cannot redeem it either, because a Joker exchange swaps a natural tile for a Joker sitting in an exposure, and a Joker in the discards is in nobody's exposure.

What the discarder says

Throwing a Joker is still a discard, and a discard is named. The player may say Joker, may say same, or may repeat the name of the tile thrown just before it. None of those opens a call. However it is announced, a thrown Joker is still a Joker and still dead.

The one wrinkle: a misnamed Joker

There is a single curious case. Outside those accepted ways of announcing it, suppose a player throws a Joker and misnames it as an ordinary tile, and another player calls that tile for Mahjong. The caller has not truly claimed the Joker, because a discarded Joker can never be claimed. The misnaming player still pays four times the value of the hand, the game ends, and the caller collects. It is the penalty for misnaming, not a way to rescue the Joker.

Why a Joker is the safest throw at the table

Because nobody can ever call it, a discarded Joker is the one tile that is perfectly safe to throw. That is useful knowledge on a hand you are not going to win and are trying not to feed anyone else's. It is also why strong players rarely throw one on a hand they still hope to finish. A Joker fills any group of three or more, and letting it go means giving up the most flexible tile you own, for good.

So when a Joker hits the table, do not reach for it and do not sigh too loudly. It is gone for everyone equally, and that, in its way, is the fairest thing about it.
