I know there are plenty of Japanese puns based on homophones, but I was wondering if there are any written puns that depend on reading one kanji character as two. For example, 校 could alternatively be read as 木交, if there was ever a context where both could make sense. Or, in vertical writing, 分 could be read as 八刀. Are there any such cases of dual readings, especially ones producing amusing or clever changes in meaning?
