think you've had a bad day?

--------------------

A giant octopus almost ate a submarine when the £75,000 craft invaded its territory. The 18-foot sea monster wrapped its tentacles around the remote-controlled sub's cable and hauled itself towards it, then grabbed the vehicle and tried to bite through its metal skin. The sub's amazed controllers used its thrusters to fire sand and grit from the seabed at the octopus, forcing it to let go. When they got the vehicle to the surface, they found two pieces of tentacle, each as thick as a man's arm, still attached to it.
