If I may ask. What exactly is the "proper" use of ^{[citation NOT needed]}, if it isn't proper to use it as a joke, as in "The sky is blue^{[citation NOT needed]}"? This article goes to some pains to point out what the improper usage of the template is, but I notice an utter lack of examples of proper usage under the "Proper Usage" subheading. --2600:100D:B061:F1CA:63A4:5BDC:F551:A703 (talk) 21:33, 5 June 2022 (UTC)
