It depends on your ability to come up with an alternate force-multiplier to the offered weapon to establish some kind of tactical superiority. If you quickly come up with one, or are at least confident of your ability to do so, the smart move is to induce the others to deal with each other first, then attack the winner from a position of strength after he has been weakened by the initial exchange with his first opponent. Otherwise, pick up the offered weapon; then the ideal strategy is still probably to see if you can get the other two to attack each other before coming after you, perhaps acting as though your only reason for picking up the weapon is to be a “coward” who wishes to avoid a fight altogether—because, of course, the other two are unlikely to go after the more dangerous opponent first, even though collaborating to eliminate the primary threat before attempting to finish off a (hopefully) weakened remaining foe is probably the winning strategy for them.
Of course, the real smart move, if you can get everyone in on it, might be to ensure that all three of you collaborate in a surprise attack on the Joker after giving him the impression he’s safe by pretending to initially target each other. That’s pretty damned unlikely to happen, though, given the level of trust most likely needed to achieve that kind of alliance without cluing in the Joker and getting yourself killed by him instead of the other two.
In general, it is a smart move to precommit to mutual support against opponents attempting to sow dissension. Of course, how effective this is depends on how reliably individuals in the group can precommit and how effectively they can signal reliable precommitment. (Also, insert obligatory UDT reference here.)
