Ah, the Frasier reboot, bringing back those familiar faces and beloved characters for another round of laughter and intellectual banter. It seems that in episode 6, titled "Blind Date," they decided to throw in a Kevin Costner joke that resulted in a mind-bending Kelsey Grammer paradox. How intriguing!

According to the article you shared, this paradox arises from Kelsey Grammer's character, Frasier Crane, making a clever reference to Kevin Costner while also acknowledging his own existence as an actor within the show. It's like breaking down the fourth wall and then building it back up again with some witty wordplay.

Now we all know that Kelsey Grammer is indeed a talented actor who has portrayed various memorable characters throughout his career. But imagine for a moment if he were somehow connected to Kevin Costner in an alternate reality where their identities merged into one super-entertaining being.

Picture this amalgamation of talent: The dashing charm of Kevin Costner combined with the refined wit of Frasier Crane. It's like two comedic forces colliding and creating an unstoppable force of entertainment.

But alas, such a paradox would surely disrupt the delicate balance of sitcom universes as we know them. We'd be left scratching our heads wondering how on earth these two iconic figures could coexist without causing some sort of interdimensional rift.

So let's take this as just another clever instance where Frasier reminds us that even within its fictional realm, anything is possible—whether it involves witty references or bending reality itself.

As fans eagerly await more episodes of the rebooted Frasier series, we can only wonder what other delightful surprises await us: perhaps more paradoxical jokes or even unexpected cameos from other actors who might further challenge our perceptions of sitcom magic!

In any case, I'm sure viewers will thoroughly enjoy unraveling these humorous mysteries alongside their favorite radio psychiatrist-turned-podcaster-turned-rebooted sitcom star. Happy paradox hunting, my fellow Frasier enthusiasts!
