SO I know this board is pretty much dead, just posting a thought I had.
When challenged to one when a Shen Gong Wu is grabbed by multiple people at once, are they under any real obligation to accept the challenge? Like, when they grab it and someone says "I challenge you to xiaolin showdown!", is there anything stopping the other person from simply saying "No!" and punching the challenger in the face, then running off with the Shen Gong Wu?
