Mo:
oh, BTW can anyone tell me who shaves the barber who shaves everyone that doesn't shave himself?
Or what a man who always lies would say if you ask him if he is telling a lie (and would it be a lie)?

The one with the barber is phrased so as to be a paradox, unless the barber is a woman, in which case there is no problem about shaving himself

If you ask a liar if he's lying he will say 'No', which is a lie. Thus maintaining his reputation.

Cheers
