You know exactly where to look when you need a few spare bits of change. It's a hassle, having to walk all the way home to get it, but at least you've found a phone you can use. You march home and walk inside, picking your phone up from a table by the door as you go. You dig one hand deep into the cushions of your couch and pull back eight or nine dollars worth of assorted change. Sensing that perhaps the plunge is worth it, you reach it with both hands, pulling out even more. Next you're wriggling between the cushions, searching deeper and deeper, pulling out hundreds of dollars. You search as deep as you can. You didn't realize the couch even had this much space inside of it. You plunge your face in, then your torso, your whole body. You've found a pocket dimension containing all of the lost change ever minted, but there is a down side. Now that you're in this pocket dimension, you'll have to wait for an explorative hand to reach in and pull you out. There are cheetos and other snack foods you can eat and any selection of drinks floating through the weightless air, so you can make yourself comfortable for the wait.
