i am the best liar you've ever met.

I am just referring to this as on the spot lying, like telling parents why i am going to be late coming home, or looking after drunk friends.
well i just dled a movie and can't wait to watch it: The invention of lying.
Staring the brillant Ricky Gervais. The basic plot is that they live in a world where ever one tells the truth, until a person invents lying and gets away with alot of shizz..
