Serge features on stickers on the doors of trains on the Paris Metro system, warning travellers that “tu risques de te faire pincer très fort” (you risk a very hard pinch) if they get between train doors that are closing.
But now Serge, who has been the mascot of the Paris Metro since 1977 and has his own Twitter account, has been given a bit of a feminist makeover and is issuing another warning.
Parisienne artist Zoia, 20, has created her own set of stickers warning against groping on the Metro.
In the stickers, Serge is pictured between two lady rabbits, one of whom brandishes a baseball bat while warning him: “Attention! Ne mets pas tes mains sur mon corps, tu risques de te faire défoncer très fort!” (Warning! Don't put your hands on my body or you risk a very hard wallop!”
Sexual harassment on the Paris Metro is an ongoing problem with a survey in 2017 showing that almost half of women had suffered unwanted attention, groping of threats while travelling on the Metro.
RATP has stepped up security in the face of complaints from fed-up commuters, adding more cameras to the network and extra employees.
Zoia's stickers are being put up on the Metro, but also in bars, cafés and on posters and you can even buy a T-shirt version of it.
