Oh for goodness sakes, get down off that crucifix, someone needs the wood!

Our reading
An editorial interpretation.
Felicia teases someone for being melodramatic. Telling them to get off the crucifix compares their suffering to martyrdom, and the wood punchline says someone else could put that wood to better use. It's a sharp, camp way of saying stop playing the martyr.
