Satchmo’s plan is absurd. He’s thought of everything that might go wrong, and he’s assuming that everything
will go wrong. But the absurdity isn’t necessarily humorous in this story. Rather, it highlights just how terrified Satchmo is, as this situation is deadly serious to him. It might be funny to think of a dog trying to be vicious and doggy paddle at the same time, but it shows that Satchmo is far too afraid to realize that he’s being ridiculous.
