my mother made a mail box out of a large blue painted cardboard box for me to "wear" for one holloween. The person giving the candy would open the slot as if to mail a letter, but instead, put the candy in the slot and it went into a small box taped inside. It was real neat, just missed (we were too late) a costume contest where I'm sure i would have won some sort of prize. some guy down the street liked it so well he gave me extra candy, which later turned out to be SOAP! that is one that I will always remember.
