"Le dimanche, c’est le jour de la messe mais dorénavant ça sera aussi celui de la pin-up. Ça avait d’ailleurs commencé officieusement dimanche dernier. Mais aujourd’hui est le premier jour officiel d’une tradition que j’espère maintenir le plus longtemps possible."

("Sunday is mass day, but from now on it'll be Pin-Up Day as well. In fact, it already had unofficially begun last Sunday [picture n°1]. But today is the first official day of a tradition that I hope to maintain for as long as possible.")
