16. What does Jonouchi drop in the hallway after thanking Yugi for being his friend in Duel One?
From Quiz 'Yu-Gi-Oh!' Volume One
Answer:
His shoe
The day after the incident with Ushio and Yugi's puzzle piece, Jonouchi waits in the hallway at school for Yugi. Once he gets Yugi's attention, he tells him that he has a treasure that you "can show but you can't see." After Yugi takes a few moments trying to figure it out, Jonouchi continues, "C'mon, it's friendship. Thanks for showing me that we're friends." Yugi seems completely delighted with this, but as soon as this scene is over, Jonouchi dashes off, embarrassed and disgusted with himself for saying anything so corny. In his huge rush, he accidentally drops his shoe. Yugi picks it up and chases after him, but apparently, to Jonouchi, it was a small sacrifice, for he refuses to slow down.
