Is happiness a warm gun?

I’m happy today, I helped my brother with his first linux install, he needed xmms and little things like that. Lost in Amsterdam needed a little help finding the right flag for his purpose, the world was pretty and all is well…
I realised how incredibly content everything made me, and I remembered the lyrics to “Happiness is a warm gun“…

Is it really all about to shoot me in the back or something? Maybe I would be better off not knowing that happiness can be a warm gun, because now, it frightens me a little. Will this all go away as swiftly as it came?

For now, I’m enjoying the moment though, riding the wave of warmth, dangerous as this comfortable cloud might be :-)
