New submitter amosh writes: 'Bill Watterson was the author of the immensely popular "Calvin and Hobbes" comic strip in the 80s and 90s, until he retired and removed himself entirely from the public eye. Since his retirement in 1995, he has become a recluse, and has not drawn a published daily comic strip — until now. This week, Watterson came out of exile to draw the 2nd panel of three of Stephan Pastis' "Pearls Before Swine" strips. Watterson has lost none of his style or talent, and a fourth strip — drawn by Pastis alone and published today, June 7 — is a lovely homage to Watterson's ending of Calvin and Hobbes. The Washington Post has the story of how it all happened.'
