The songs are funny.

But give me a break!

Adverse possession is not unethical -- as every first year law student learns, this doctrine serves legitimate purposes. For example, it prompts landowners to discourage trespassing, and it rewards people who use their land, as opposed to letting it fall into disrepair.

Property ownership has its benefits and burdens -- doing something to maintain the property (i.e., kicking out trespassers) as opposed to nothing is one of those burdens.

Give it a shot - go start adversely possessing that vacant lot near your home today!
