Season 18, Episode 22 - "A Shot in the Dark"
Roz is forced to deal with the aftermath of a gun discharge, caused by a mentally unstable employee. This results in a debate to whether the employees should be allowed to bring guns in, but Roz is strongly against it. Hoping to make others feel the same way, Roz organises a trip to the local gun museum, namely the “gun safety” exhibit. It turns out to be completely different to what she had in mind, and soon several of the staff (including Bulldog) want a gun. Roz reluctantly accompanies Bulldog to the shooting range for practice, and is overcome with guilt when his inexperience results in the instructor being shot in the arm. Meanwhile, Gil reluctantly takes up paintballing with professional Denise.
