This was the hardest work we had 
to do in exchange for ramen.
.كان هذا أصعب عمل كان علينا القيام به مقابل الرامن
La tâche éreintante qu’on a dû effectuer
pour payer les ramen !
Quel lavoraccio terrificante che
 ci ha fatto fare in cambio del ramen!
Foi o trabalho mais duro que tivemos 
que fazer em troca de lámen.
Помните ту жутко тяжёлую работу,
которую мы делали за рамен?
