Chekov's Gun/Playing With

Basic Trope: Chekov's phaser in Star Trek.
 * Straight: Pavel Chekov is present and is carrying a phaser.
 * Exaggerated:
 * Chekov is dual-wielding phasers.
 * Chekov is a phaser.
 * Justified: He is on a dangerous mission and has been issued a sidearm for safety reasons.
 * Inverted:
 * Gunn Chekov has been issued a phaser.
 * Or maybe, a phaser is carrying Chekov.
 * Subverted: Chekov is told to leave his phaser on the Enterprise when he leaves...
 * Double Subverted: ...and then it turns out that Chekov's Gun is a Chekhov's Gun.
 * Parodied:
 * Every phaser on the Enterprise is property of Chekov.
 * Which, because he's sometimes referred to as the security chief, also a stretchy bit of Fridge Brilliance.
 * Deconstructed: Chekov tries to stun the alien running around the ship, but because he never uses it, he misses badly.
 * Reconstructed: All crew members, including Chekov, are required to attend target practice regularly.
 * Zig Zagged: There is a gun, and there is a guy, but nobody is really sure what the guy's name is or what type of gun it is.
 * Averted:
 * Everyone has a phaser, but nobody is named Chekov.
 * There is a Chekov, but he doesn't have a gun.
 * No one is named Chekov and there are no guns.
 * Enforced: Chekov is in a Massive Multiplayer Crossover and takes his phaser with him.
 * Lampshaded: Spock says "it was only logical to assume that Chekov would be carrying a phaser in this situation."
 * Invoked: Kirk issues Chekov a phaser.
 * Defied: The Organians disable Chekov's phaser so he can't use it.
 * Discussed: Wesley Crusher to Picard: "Can I have a phaser? Even Chekov got one on the original Enterprise."
 * Conversed:
 * "I knew it! Chekov had a phaser on him the whole time!"
 * "I had a feeling Chekov's gun would come in handy sometime."
 * Played For Laughs: Chekov always has a phaser on him, even in the shower.
 * Played For Drama: Chekov single-handedly saves the ship, Rambo-style, using only his phaser.
 * Plotted A Good Waste: Chekov's gun is a major plot device.

Playing With Chekov's Gun is not recommended. He has many hours of training; you might seriously hurt yourself or others.
