Never point a gun at someone unless you plan to shoot them.
I'm not a big fan of guns but this guy was going to buy me one no matter how much I refused. It's kept in his safe and he has practically forced me to learn about it. I usually shoot a round or two and then get bored. The most I can say about the gun is that it's cute, but I don't carry it around.
I used to have a little model gun about a quarter the size of that on my key-ring, and one time at the airport the security dude spent about 5 minutes inspecting it with a none too impressed look on his face. :s
