So, back in the day when Marko and I were roomies, I got my first electric airsoft gun, an HK MP5SD3 at a local gun show.
I was working at Montague Gunsmithing at the time, and we took it into the back room at the shop to try it out, since we had a pellet trap set up back there on which we could hang targets. I loaded a mag, hung a target, and ripped off a couple of short bursts. "Whoah! This is cool!"
"Hey, let me try it," says Marko.
At the time, I didn't know you weren't supposed to recycle pellets, so I handed it to him, saying "Sure, just let me go downrange first and pick up a couple of those pellets before you shoot." I strolled down towards the target and bent over to scoop up some of the little plastic BBs. As I did so, I thought to myself "Oh, no. I'm down here bent over with my butt in the air, and I just handed him a loaded... OWWWWW!"
With as much dignity as I could muster, I strolled back to the firing line with my hand held out. "Gimme the gun, dude."
"No way. You'll shoot me with it."
"We live in the same apartment. I know where you sleep. Heck, I know where you shower. You can take it like a man now, or from ambush later."
*sigh* "Okay, here."
I'll say this for him, he's a mensch; he didn't even flinch.
Good times, good times. :)
