I tell people all the time.. "Do you remember when you could bullshit anyone." Now they just type your BS into their smart phone.
It's an art now though. You have to pick little tidbits that SOUND plausible but you can never really verify.
I, for example, told my (American) flatmate months ago that no living person other than current sitting monarch can appear on a British postage stamp. Had to backtrack when the Royal Mail announced every British gold medal winner at London 2012 would get their own stamp.

It's unbelievable how many "facts" nowadays lead to some lone blog or wiki article with no references.
