Calvin and Hobbes by Bill Watterson for September 30, 1989
Rosalyn: Calvin, you let me back in the house this instant! Calvin: Don't worry, Rosalyn! There's only a 50% chance of rain tonight! Ha ha! Hobbes: She trying to open the downstairs windows. Calvin: It's ok. I already locked them. Rosalyn: You open that door! Calvin: Hey Roz! What's in your purse? Mind if we look??
