Concrete culvert /pipe

I stopped at a lady's house once who had some freebie stuff out to the road, she invited me back to the backyard to start pulling more stuff, she said "Here.. Look at this pipe, it has metal in it" It was a concrete pipe with re-rod in it. I hit it with a 10 lb sledge and cracked it, I hit it again and finally busted a few pieces off it. I said "I appreciate it but that thing is no where near the work to get the ..35 cents out of it!
