In this case the Jackdaw is the joke. Aslan is a lion in the book but a symbol of more.
I recommend you read the book. It is a simple children's book but has some insights into cosmology .
If you don't have the book near you then perhaps you can find an ebook like:

Or check Internet archive https://archive.org for "The Magician's Nephew." The joke part is chapter 10.
Oh my.. Thanks A lot. I'll definitely check it Out and have Myself a little laugh
It's really worth reading and only a few pages. It's on of the first fantasy books.
Oh... and you can comment in Spanish if you like. Of course... English is a lot easier for me to catch.
¡Oh! ¿tu hablas español? eso es asombroso😎😂
Sí, pero cuando estoy ocupado veo que a veces me pierdo los comentarios. Mucha gente en Chicago habla español.
