Brother Bait

We got some Brother bait yesterday, three issues of the comic that stars that cat he likes so much.  We've been getting texts all evening, complaining about hearing the rustling of pages, and demanding to know what we are reading.  How long do you think we should let him go before starting talking about Dex-Starr so he'll realize what books we have in our paws, and will want to come rushing over to  get them away from us?
