That reminds me of something I did to my younger brother after we had got into some squabble over lord knows what. I had taken one of those tube style Bic ball point pens and took the guts out, it was simply a plastic tube at this point. I had a Crosman Powermaster 66 and I inserted a spitwad in the pen tube, then inserted the pen tube into the muzzle of the air rifle and scotch taped around it to secure it. I then pumped it up and found him sitting on the couch watching TV. I fired at him from probably 50 feet away or so and it got him right in the neck. He was bleeding pretty good from it, and flopping around on the ground squealing like a stuck pig. I had no idea a spitwad would come out of my creation with that amount of force or accuracy, and I felt bad for doing it afterwards.
