It all starts when some kid decides to buy four turtles, name them after famous artists and flush them down a massive toilet one after the other!
Now is this the end of our heroes? ooh no! the sewers happen to be radioactive, because what sewer is complete without being radioactive I ask you?
And does this radioactivity Ionise their cells and give them cancer? ooh no! it makes them grow massive, stand upright, de-evolves their shell to the point of being useless and evolves their vocal cords so they can speak! oh the wonders of radioactivity!
Now, in these crazy sewers they find a giant rat who can speak English! and does this rat attack them? ooh no! it becomes their master and teaches them Kung fU, THEN IT ARMS THE TURTLES WITH WEAPONS!
Now, do the turtles have revenge upon the heartless child who flushed them down the toilet? ooh no! the child is forgiven and they start a war with a bunch of SHADOW WARRIORS oooooh! because fighting is fun!
and that pretty much concludes the story of the teenage mutant ninja turtles!
Terry: Yeh, the story is so realistic isnt it?
Bob: I KNOW! I cant believe it isnt real!
