Freleng and Pierce this time. Bugs escapes hunters (who then vanish from proceedings) only to pop up inside a prison (another of those convenient rabbit holes). Usual formula ensues, with Sam as the antagonist - though before long I suspect Bugs has forgotten all about the hunters, or even escaping, and is just delighting in making Sam's life a misery.
To be honest, it's a bit ordinary. I can't think of much else to say about it. It's not bad, but it's the umpeenth minor variation on this story, and if I'm going to watch a Bugs short, I'd rather pick a good one.
