I would place one Portal on a rocket that got shoot into space and the other one direct under Osama Bin Laden’s feet,so that all the fuckin’ Taliban-assholes would get pulled into the deep deep space and explode painfully because of the vacuum
Other possibilty:
One Portal in the bathroom and one in my room.
If I would have two Portalguns:
One Portal in the kitchen and one in my room.
