Target practice

The crew of the flagship of the Tenth Sontaran Battle Fleet intended to use the students of Rattigan Academy as target practice. Fortunately for Luke Rattigan's followers, they all abandoned him before they could be teleported to the Sontarans. (TV: The Poison Sky)

The firing range at Torchwood Cardiff used pictures of Weevils as target practice. (TV: Everything Changes, PROSE: The Undertaker's Gift)

Upon his dog, Gnasher, painting a red target onto a police officer's posterior, Dennis the Menace remarked that it was "good of Gnasher to help [him] with some target practice". He then launched the spikes from a cactus into the officer's posterior, causing him to jump into the air in pain. (NOTVALID: Dennis the Menace in Balloonatics)
