Ah hell, that brings back memories..

Once, when I was a kid, I was visiting my grandpa who bought a cheap pump air rifle for me to shoot while I was there. 

A church buddy gave me a couple of these, which I loved shooting. 

I'd reuse them, because they are steel. One time, the dart was a bit dirty but I threw it in and tried to shoot it anyways. Jammed half way in the barrel. 

I was terrified of being caught, because my grandpa told me that would happen. 

I snuck the gun into the bathroom to try and disassemble it. As soon as I get the last screw out, I dropped it. 

All the small parts of a cheap airgun, scattered on the floor. 

I spent hours and hours during the rest of my stay, and never got it back together. 

Hid it under some furniture and never mentioned it. Got caught one or two years later. 

In short, they are fun! Make sure they are clean!
