I believe everybody in the world should have guns. Citizens should have bazookas and rocket launchers too. I believe that all citizens should have their weapons of choice. However, I also believe that only I should have the ammunition. Because frankly, I wouldn't trust the rest of the goobers with anything more dangerous than string.

In this deliberately hyperbolic, deadpan riff, Adams satirizes absolutist rhetoric around gun rights by pushing it to an absurd extreme: not only should everyone have any weapon they want, but the speaker alone should control the ammunition. The punchline exposes a tension between professed faith in “citizens” and a simultaneous distrust of other people’s judgment (“goobers”). Read as political humor, it suggests that calls for maximal armament often smuggle in assumptions about who is “responsible” enough to wield power—while the speaker exempts himself from the standards he applies to others. The joke also plays on the difference between nominal rights (owning weapons) and practical capability (having ammo).
