For the record, like my Warren posts, I'm pretty much done posting EC stories mainly because most of them wouldn't be as effective under the new 1/3-per-story rule. That being said, I'm making a brief exception to this with the following story mainly because of how cracky it is.
So basically, the story revolves around two twins Cynthia and Carl who, despite being of different genders, look similar enough that it's easy to fool people into thinking that they are the other twin when wearing each other's clothes (as the preview pic shows).
The two part when Carl refuses to work as a clerk to support Cynthia and his mother. Carl wants to live his own life but eventually becomes a bum. One day, he discovers that his sister has married a millionaire. When he visits Cynthia for help, she refuses on account of how he deserted her when she needed him the most. She gives him a hundred dollars out of pity and sends him on his way, which infuriates Carl. He comes up with a plan to switch places with her once he realizes that her husband has left his entire estate to her in his will...
