Mount Rodney
You may think that this is a name of a mountain, but you're wrong.
Its the name of a secret police organization who responsible for protecting the world from aliens and magical entities.
Mount Rodney is a long name so they decided to give a short name that doesn't sound funny or stupid. "Mr-10" (pronounce as 'mister ten') is the their short name. But it does sound a bit funny.
I have written this story about a year ago but I forgot many of its original idea.
