Checkered Past

In what turns out to be a REALLY bad stroke of luck, Superman loses his powers and then forgets that he was ever Superman! Luckily plain old Clark Kent is up to the task of wearing down a mournful Lois until she consents to marry him. And that's just the tip of the iceberg! It's Superman 192 and 194, and don't panic, it's an imaginary story (BUT AREN'T THEY ALL?)
