loopy loop

read something interesting in a book, this is a question which goes in a loop;

if a barber shaves all men who do not shave themselves, who shaves the barber?
.
.
.
.
.
.
if u say 'he shaves himself', then u'r caught,
as

'the barber shaves only those men who do not shave themseleves'
(so if he shaved himself, he's not one of those men who do not shave themselves)
.
.
.
.

if you're getting lost, repeat the lines to digest the web !!
.
.
.
.
next guess - 'he doesn't shave himself, so somebody else shaves him'
.
.
.
you think you caught it, but u'r caught again;

he shaves ALL men who do not shave themselves
(and those who shave themselves, must have shaved), so nobody is left to shave the poor barber, resultant ;
.
.
.
.
question remains - Who shaves the barber??
