Costello is a 10 year old bulldog Mastiff who is an integral part of The Huberman Lab podcast. He is often asleep and has a superpower of getting everyone else to do things for him without doing anything himself, which I call the Costello effect.

You know, Costello, much like David Goggins is a person, but Goggins also has grown into kind of a verb. You're going to Goggins this, or you're going to, and there's an adjective, like that's extreme. Like I think that for me, Costello was all those things. He was a being, he was his own being. He was a noun, a verb and an adjective.

If you've been hearing Costello snoring throughout this episode, I apologize on his behalf. As I said in the welcome video to this podcast, he's an integral part of the podcast. A few people have said, hey, that noise in the background is really disruptive. Hey, what can I say? Costello is a 10 year old bulldog Mastiff.

This is his state for most of the time. He is highly, he's asleep still. So some of you have asked to see Costello. If you're just listening on audio, maybe he'll give us a... That's a, oh, okay, we're going to let him get back to sleep. He's always here. Some of you have asked to see him. Costello's not a pot smoker either.

And in fact, just as a brief anecdote, I can remember when Costello was a puppy and I was entirely responsible for his wellbeing, like any parent of any infant, I lost my appetite for those few weeks when I was house training him, and I seemed to lose all ability to process any cognitive information.

So, and he had this amazing superpower that I wish I could get, which is this ability to get everyone else to do things for you without doing a damn thing. The Costello effect, as I call it. So it's an idea I hope he lives on. Yes. Thank you for that. This actually has been very therapeutic for me. Which actually brings me to a question, we're friends, we're not just co-scientists, colleagues working on a project together and in the world, that's somewhat similar, just two dogs, just two dogs basically.
