Riddle/paradox?

There is a barber and he has a sign on the window, it reads "I only shave those who do not shave themselves" Does he shave himself?

Yes= he shaves himself but he only shaves those who don't shave themselves therefore he doesn't shave himself.
No= He doesn''t shave himself but he shaves people who don't shave themselves, therefore he must shave himself.
??????????????????????????????...

I 'only' shave does not mean, i must shave. Just because the barber will not shave people who shave themselves doesnt mean that he must shave those who dont shave themselves.

Therefore he doesnt shave himself, someone else does. Probably his wife Letitia.
