While we can't know for sure what he enjoyed, we can make some educated guesses based on his style and themes:
* Humor: Dr. Seuss was known for his whimsical and absurd humor. He might have enjoyed strips with similar qualities, like Peanuts (for its philosophical humor) or Beetle Bailey (for its slapstick).
* Imagination: His stories are full of fantastical creatures and imaginative scenarios. He might have appreciated strips like Calvin and Hobbes (for its fantastical adventures) or The Far Side (for its surreal humor).
* Social Commentary: While often subtle, Dr. Seuss's work sometimes contained social commentary. He might have enjoyed strips with similar themes, like Doonesbury (for its political satire) or Bloom County (for its social commentary).
Ultimately, we can only speculate about Dr. Seuss's favorite comic strip. But knowing his work, we can make some educated guesses about the kind of strips he might have enjoyed.
