Isao Kondo dresses up like Danpei Tange and tries to encourage Gintoki (which he keeps refering as Joe). Gintoki is however every pessimistic about the situation and even says that he has no tomorrow. (sort of reflects how in Ashita No Joe, they are fighting for tomorrow)

(Not to mention Ashita is tomorrow in japanese duh)
