Calvin and Hobbes by Bill Watterson for May 10, 1987
Calvin: Ever notice how different the air smells after a good rain? It smells like...like...dead worms! Wow! Look at the size of that puddle! Wahoo! Ha ha ha ha ha Sploosh splash sploosh splash hee hee hee he ha ha ha. Rats. My underwear's all soaked. Now it's gonna itch and ride up my rear all afternoon. Well, it was worth it! Hobbes: That's why I never wear the stuff.
