While taking their usual bath, the boys discuss how much Kyotaro is like an old man. The next day, when they go to school, they find themselves exhausted by climbing up the stairs... and learn that they're all becoming old men!
but you've gotten even worse 
in your old age, Ichiro.
لكنّك ازددتَ سوءاً حتّى في شيخوختك يا إتشيرو
aber im Alter wird es
immer schlimmer, was, Chiro?
pero has empeorado con la edad, Ichiro.
pero has empeorado con la edad, Ichiro.
mais là, Ichiro,
tu deviens complètement gaga.
ma sei addirittura peggiorato con l'età, Ichiro.
mas você ficou ainda pior com a idade, Ichiro.
а в старости так совсем поглупел, Итиро.
