Matsutaro had decided to become a sumo wrestler to impress Reiko, the lady of his dreams. But he's still not all that enthused about the whole idea. One evening he spends some time with a wrestler-to-be, Tanaka, who happens to be laid out with a cold. They play chess together and Matsutaro in a tantrum makes him cry; feeling bad for that, Matsutaro decides to help Tanaka make the beds for their stable-mates. Boredom sets in after the stable-mates return, so Matsutaro says they should pull a prank on the ani-deshis upstairs...
Those seniors act all high and mighty,
Diese Ani-Deshi sind hochmütig und benutzen
 ihre Untergebenen wie es ihnen passt.
Esos ani-deshi actúan muy orgullosos 
y usan a los demás como quieren.
Esos ani-deshi se lo tienen muy creído 
y usan a los demás como quieren.
Esses veteranos são muito mandões, 
e fazem o que bem entendem conosco.
