Didn't rerad all the comments, but did anyone mention the moron that fired a
bullet through the wall for his cable? Killed his wife with a clean shot. I
wonder if the guy had any cable parts laying around?

I once pounded a 4" or 5" hole in 10" of solid concrete for a dryer vent. That
took a cold chisel, 24oz hammer, and a lot of beer. I didn't know i couldn't do
it....so I did it! My arms were like Jello after that.

If you don't mind the noise, a ,22 rifle can get the job done. Watch
out for block & bullets bouncing
