While a group of people in the Netherlands attempted to set a new world's record of dominoes, a sparrow flew in and knocked over 23,000 of the dominoes.

An angry Dutchman retrieved his air gun, cornered the sparrow, and shot it.

Now, animal rights activists are investigating the matter. Endemol, the TV firm which organised the event, defended the killing, saying more than 100 people had worked for more than a month setting up the dominoes.
