22 most traumatizing things seen on the Paris metro etc.

I love Les Inrockuptibles's L'anti-guide de Paris. http://blogs.lesinrocks.com/antiguideparis/
I'm so stealing their ideas to make my own lists. I'm sure I can come up with 22 traumatizing or just plain weird things I've seen on the metro. F.ex. today I saw a geisha and the angriest, most stressed looking dog ever (very sturdily muzzeld, thank god).
