Blake is right about one thing: the homicide division never found the body of the high-school friend to whom he one time lent that particular magazine.
Because Blake isn't actually that much of a psycho. I'm sure that friend never got loaned porn again, and probably got a blistering talking-to (Blake might've even had Charlie help him with the words, and Charlie can be vicious), but Blake is trusting that Toni will know he's kidding.
If Sarah had been in the room still, this might not have been wise.
