Overhearing conversations on buses, in cafes, etc, sometimes gives an interesting glimps into the way people think - sometimes ideas, concepts and facts get formed in people's head and it's easy to forget and take for granted knowledge gleened over years of life experiences.  Sometimes facts can be partially learned and for what ever reason your imagination has to fill the missing gaps - especially when you're talking to friends or peers and pretending you actually know what you're talking about.  I have over time heard conversations which made me spit my tea, not because of the content but because of the genius of their inaccuracy to the facts.  Here a couple of these gems of knowledge:

•  The film "It's all gone a bit Pete Tong" is based on the Radio 1 DJ Pete Tong, and he really does a fantastic job considering he's deaf.
  
  
• Everybody in the world has a unique PIN number for their bank cash cards, (yes all 9999 people), and if you managed to get somebodies pin number you can actually put your card in the machine - enter their PIN and remove money from their accounts.
  
  
• Limes are infact unripe Lemons - which are deliberately picked early to give them that colour.

This is just a small selection but I could go on all day long but I won't, has anyone else overheard any blinding facts.
