Cleese is a lawyer and a shrink?
Cleese is a genius and the cleverest of the Pythons in my humble opinion. However, I don't think he is a shrink - he has written books such as "Families and How to Survive Them", which he co-authored with his own shrink Robin Skynner, but he possesses no qualifications himself.
As far as I know he never actually practised law either - the lure of showbiz drew him away too soon. He certainly was a believable barrister in "A Fish Called Wanda" though!!
Graham Chapman was the python who did practise, but in his case it was medicine, not law.
