Try to take over the world...and make people fall 5,000 feet onto a slab of concrete.

Whenever I go on holiday, I'll shoot the blue portal into my house.
Then when I'm at the location in question, I can shoot the Orange Portal to go back and visit my own house and make sure it hasn't been burgled.
Let's face it, I'm a paranoid man. Plus it would save on the return flight.
