Big Bang? more like ginger nuts.

I have a theory as to why all the dinosaurs became extinct, forget the Big Bang theory.  My guess is they were all doing really well until one night after a shopping trip to Coles in Sydney mummy dinosaur brought home a packet of "Arnotts Ginger Nut Biscuits". They promptly had a biscuit each and broke all their teeth, thus rendering them unable to eat their staple diet of Roo meat, thin end of the wedge as they got passed around the rest of the family I reckon. Those people at Arnott's have some explaining to do I can tell you.

They make 'em tough in Australia :-)
