Well for starters i would probably take a moment and praise cthulu for granting my wishes, but after that i move swiftly.
I would sneak up behind you and pull your mask down so that it shifts the eye holes and disorients you. While you bring your hands up to try and fix it, i grab and hold them underneath my right arm as i start to tape your wrists together and then start to coil it all the way up to your elbows. Once thats done i let you go and watch as you stumble for a bit; dazed and confused at your sudden loss of vision and the use of your hands. Thats when i sneak around and trip you. I start to tape your ankles and then your knees. To finally secure my trophy, i pick you up and carry you to trunk in the corner of the room, as i set you down in there, i pull off your mask to get a good look at you before i call for the police. As i look at your pretty eyes, i decide that the cops dont have to know just yet

so i pack as much of the mask as i can into your mouth and then tape it in place nice and tight. "Thanks for visiting", i say as i close the lid to the trunk, lock it, and then go get a mid-night snack
