You create a large portal that let's you walk right through the wall to your neighbor's aparment. Shari has been a pain in your backside ever since she moved in and you decide it's time to get her back. You sneak up to her bed, where she is sleeping (entirely in the nude, you notice). You gently seal a portal over her mouth, the other end of which is still attached to your butt. You return to your apartment after leaving a polarized spy portal in her room. You know you're going to want to watch the fun.
