[Oh Haha]

Son: "What is a green thing that looks like a pop bottle but it started smoking when I hit it on rock?"

Me: "I have no idea, I would need to see it to know it. Where did you find it?"
Son: "In the field down the road."
Me: "You know you are grounded today, right"
Son "Yeah,but......
Me. GRRRRRRRR

After dinner, he brings the green thing into the house to show me. I immediately smell that familiar aroma of LP. WTF?!!!!!!!

He's lucky the tank didn't rupture when he was throwing it onto the rocks.

I have it outside bleeding the rest of the tank contents.
