Gary briefly turned against the new tennis racket bug zappers. They make a zap noise but don't cause any flies to drop out of the air. I don't know if the fly explodes into atoms, or is re-energized and files off stronger.
After he turned against the rackets, Gary bought some heavy artillery: a Bug-A-salt -gun. It's a little toy long gun that fires a barrage of table salt at flies, preferably from behind. The videos are all of shots in the back. Then the fly dies from a dozen painful salty wounds.
I found the gun in the trash the day it arrived. "'IT'S A GUN!" Gary explained. "I WILL NOT HAVE A GUN IN THIS HOUSE." It was clearly marked as a gun when he bought it, though, so I didn't know what caused the gun reversal. The only thing that stops a fly with a gun is a good guy with a gun, right?
I got the gun and its packaging out of the trash bin. It was clearly a toy gun. Plastic, colorful, orange tip, requiring no license or background check, and loaded with table salt ammunition.
Then I read the packaging. They leaned heavily on the gun metaphor. Also, half the packaging is a manifesto on why flies deserve to die. Then there are the cautions about not Shooting Your Eye Out, and there's a safety on the gun so it doesn't go off unexpectedly, and when Gary saw that he had to pump the thing like a pump-action shotgun, he dropped it in horror into the trash bin.
I brought it back in and danced around the house for a while in various Charlie's Angels poses, but I was unable to get it to fire. Gary went into debug mode, showed me I wasn't returning the pump to the right position, used aluminum foil to prove salt was coming out, and now he's interested in the gun again.
I doubt we'll be able to use the sight and kill a bug from three feet away. More likely I'll take the finish off the furniture inside and salt the earth outside.
