Well, this problem has plagued me for years. Actually, I have never been trick-or-treating in my entire life as I had a very hard and strange childhood and then never had human children as an adult (yes, I have thought of taking the Husky or Puppy the Guinea Pig, but have never followed through!).
Well, I recently saw a video that demonstrates the perfect solution to this problem..I'm gonna do it this Halloween! So funny...enjoy!
