As Calvin has often proved, actions speak louder than words.
“Thank Heaven for little girls
No matter where, no matter who
Without them what
Would little boys do?"
Calvin has his own interpretation of those lyrics – in common with many other boys in comic strips and in real life.
Calvin is far more likely to thank Heaven for tigers than little girls. Of course, he can’t understand why people keep thinking Hobbes is a stuffed tiger.
The same can be said of Flo. She’s far more successful than he is in both areas.
P G Wodehouse used it in his “Jeeves” books. In a story from an early collection, Bertie asks Jeeves how he gets his amazing intellect and Jeeves tells Bertie that it comes from a diet of fish. Jeeves is probably taking advantage of Bertie’s gullibility but Bertie believes him and repeats it to others in later stories.
He doesn’t need one as he’s much wiser than Red.
Maybe an arsenal of ideas would be more accurate.
He could use his magic to create indoor rain in the shower but that wouldn’t have been as funny. Perhaps he wanted to do it that way to see his wife’s reaction.
He may not have used a ladder. He may have been able to use magic to get into the sink but not to fix the shower. We all know that his power is limited but sometimes very strong.
