Cover art for Trigger Happy lyrics by Weird Al Yankovic

I love this song. Done in the style of the beach boys I believe it's in reference to people who love guns and are indeed a bit to eager to use it at any given opportunity.

In another of weird al's songs 'canadian idiot' he comments how Canadians (don't even take their guns to the mall?)

So possibly a comment on the ease in which guns are obtained in America and used in self defence often by mistake. (poor kitty)

Guns are not often used in self-defense by mistake. They are used about 2.5 millions times a year for self-defense according to the FBI and Department of Justice.

Whereas only about 13,000 people die from being shot every year (this include police, criminals, law-abiding citizens in self-defense, and accidents by any of the previous three).

Contrast that to the hundreds of thousands of deaths related to driving every year and you might find a REAL issue is texting/drinking while driving...

Also, 49 states allow some way for a normal citizen to carry a firearm for self-defense. Illinois is the only state...
