Les Oranges Et Les Citrons

Professor Calculus's friend develops a blue-skinned orange that can grow on any kind of land and survive harsh weather (in the manner of Lue Gim Gong) and therefore solve world hunger. The Professor and his friends, however, run afoul of gangsters who also covet the fruit. The adventure takes them from their home in Marlinspike Hall (Moulinsart), a fictional mansion that is presumably in Belgium, to Spain, where Calculus and another scientist are kidnapped.

After getting into a scuffle with his boss and some co-workers, an orange packer tries to help another co-worker, only to wind up in a conflict with him as well. Trying to elude his boss, he heads inside the packing house, and visits with the women who are packing fruit into cases. Then he heads to a storage area, and tries to use the machinery to escape his pursuers.
