Batman is under the earth

I had a crippling fear of being buried alive when I was a kid, and a lot of that came from reading non-fiction accounts of Victorian nightmares at a worryingly young age. But a lot of it also comes from this fairly innocuous issue of World's Finest:

Issue #267 of the long-running Superman/Batman comic has the dark night detective overcome and placed in the most simple of all death traps - a buried coffin. And there was something uniquely horrifying about Batman being under their feet on the cover, with nobody thinking to look down. 

Still, the gymnastic skill in squeezing his whole body around in that confined space has stuck with me as a peak Batman moment. I just hope I never have to try and do it myself.
