Ok, cast your minds back to Madain Sari... Zidane comes to Vivi and cheers him up from a sport of depression, while in the kitchen Eiko is gushing over Zidane's hotness. Then, Zidane invites Vivi to share a moment that two men do together. The camera than pans away to Eiko and repeated *tinkle-tinkle* sounds come from the two guys.
The first time I saw this scene, I thought it was funny cause they were doing something entirely normal that sounded like they were being incredibly dirty. The second time, I realised there was nothing normal that they could be doing, and they were in fact being incredibly dirty.
So, people of EoFF, I ask you to mend my innocent mind and tell me, just what were Zidane and Vivi doing?!
