If a Pathological liar told you he was a pathological liar, would you believe him?

no, i'd look for another source

yea since he's been diagnosed as a pathological liar

well, if you already know he's a pathological liar then he wouldn't need to tell you.

yea.... because he's a pathological liar

doesn't mean he tells lies all the time.......

er... i mean he tells the truth on rare occasions,

and this would be a rare occasion

maybe...
