JOKE-OGRAPHY:
1. Mary Magdalene makes early trips to Jesus's tomb, maybe to anoint His Body with funeral oils, or maybe just to cry. In this cartoon, she refers to these trips as her "mourning routine." The word "mourning" (grieving) sounds like "morning" (the early part of the day). This pun implies that Mary's early daily ritual (her "morning routine") is one of sorrow (hence, "mourning routine").
2. As Mary approaches Jesus's tomb in John's version of the story, she sees that it's open and hurries to the apostles to have them inspect it. In this cartoon, however, she's too exhausted to recognize what the open tomb implies (that the dead Jesus has somehow left His tomb). She continues into the tomb to wait for Him to return, and only after several minutes does the event literally dawn on her. This particular sunrise has seen the Son rise.
