The Rabbit of the Paris Métro (French: Lapin du métro parisien), also known as Serge the Rabbit (Serge le lapin), is a fictional character that has been used as a mascot by the RATP Group since the 1970s to promote passenger safety in the Paris Métro.
[2] Serge the Rabbit is depicted on stickers inside the train doors warning passengers against placing their fingers on the doors when they are opening.
Ne mets pas tes mains sur les portes, tu risques de te faire pincer très fort.
Do not put your hands on the doors, you risk pinching your fingers very hard.)
The rabbit design has changed over time,[3][4] with the first version of it drawn in 1977 by Anne Le Lagadec.
