What is Charles Schulz saying, that Lucy is interested in Charlie Brown's "Mangle Comics," "Disease Comics" and "Gory Comics," yet he's not interested in "The Little Bunnies," "Billy Bluebird," and "The Funny Foxes?"
Some possible takeaway points:
1. Boy's comics are ridiculously violent (although "Disease Comics" doesn't seem like the most marketable title).
2. Boy's comics are more universally interesting than girl's comics, which implies Lucy considers girls' comics to be lacking.
3. Lucy is brushing up on her evil skills. Although Charlie Brown presumably reads them all the time, and he's kind of fragile.
