Cookie to the first person to spot the Shakespeare reference.
EDIT: Cookie goes to criSTilPlatNYM, who correctly spotted that the nth line of dialogue is an anagram of the nth line of the nth sonnet. No cookie for CriSTilPlatNYM, CRiSTilPlatNYM, or criSTilPlatNYm, each of whom suggested that the bear exiting pursued by Antigonus is the reverse of what happens in The Winter's Tale. I don't know where you got that idea from; that character is never named in the comic.
