For the Man Who Has Everything/Headscratchers


 * A bit minor, but it's a little surprising that Superman isn't spending his birthday with his parents.
 * Countered by Fridge Brilliance when you remember that Superman could easily spend part of the day with his parents and part of the day at the Fortress. It's not like he has a long commute.
 * In regards to the comic version, if we're talking about the Kents, it was Pre-Crisis on Infinite Earths. Jonathan and Martha Kent died shortly before Clark went to college Pre-Crisis.
 * And for the animated one, there's also the element of Fridge Brilliance that since the Black Mercy attacked Clark while he was in the Fortress, surrounded by memorabilia of his Kryptonian heritage, it's no wonder that he dreamt of life on Krypton.
 * It's possible Superman and the Kent's celebrate the day they found him as his Earth birthday, and that this story takes place on his actual birthday.
