It is not a good idea to mess with another man's car or more specifically, don't put an axe in your mate's car. It could result in an uncontrollable desire for revenge.
The prank begins when an Aussie wakes up in the morning to find his housemate has had a heavy night and decided to put a regular axe in his beloved car. The clearly angry owner then decides to get his revenge with the use of his life savings, and a 42 foot replica axe that weighs more than a tonne.
Whilst it is certainly plausible that this whole event was staged, it is still great entertainment.
