How does a team earn 89 runs in a game that's not even over yet?
One potential problem, avoided I think, with this strip is the use of the word "home" in the last panel, which is a baseball term. Schulz plants the idea of Schroeder's home life in the reader's mind in the third panel however, which allows CB's line in the last to be more cleanly read as referring to Schroeder's house instead of home plate, would would have confused the joke.
