Beyond the grave, Bubba
Another fine example of CTer reading-comprehension difficulties
Let me get this straight; if you use the term "beyond the grave", you must believe there is life after death and that, somehow, Oswald is sending memos from that after life..... Is that what you are saying? Is that what you believe?
And since you say the return address is Hell, you must also believe Oswald is living there, right? But, hang on... if he is living there, how can he be sending memos? Wouldn't the paper burn before he had a possibility to write anything?
Fascinating... please keep on digging. This is getting interesting.... Wacky, but interesting nevertheless.
But ok... so, there is a postal service "Beyond the grave" (i.e. in Hell)?
