We were somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "The Medway Handyman"
saying something like:

I removed a cast iron bath from my father in laws years ago. I heard all
about this 'bash it with a hammer' trick, so I tried it. My ears were still
ringing a week later and the bath was unscathed!

A sledgehammer works, but watch the splinters.
