Giant woolly mammoths died out because they ran out of grass - not because they were hunted to extinction, according to scientists.
The dope smoking, gargantuan herbivores became so passive through being too huge for any other animal to mess with and skinning up such huge fatties to toke on, that they lost their edge.
"It is food for thought in these times of global warming and drug-induced habitat change," said team leader Professor Phoney McPhloonaloo.
"Mammoths had roamed and munched their way across many parts of Europe, including the UK," said Professor McPhoonaloo.
As they became more and more dependant on their daily toke, they also became less and less arsed to do anything about getting more ganja, after a while they even stopped going to the all night garage on the A5 for chocolate milk and pickled onion Monster Munch.
Extinction was inevitable.
