Well, a padlock, somebody from schools front fence, a chain = A good old laugh, and a very angry persons from schools mother... :P
In more detail... Somebody from school, who we sometimes hang around with always padlocks his front fence, so we thought we would play a bit of a joke, and help him out with another padlock on the chain. One problem...His mother didn't see the joke in it all and she was quite angry.... mainly because we didn't have a key for the padlock.... So my friend is gonna use the bolt cutters, no big deal
Good for a laugh though.
