If you're at all familiar with Burr, you know his day job as a standup comedian tends to keep him quite busy. This, obviously, makes scheduling an appearance on Better Call Saul (shot entirely in New Mexico) a bit difficult. Scheduling complications aside, it seems Burr and Better Call Saul producers actually did work out a time to get the busy funny man to Albuquerque for a Kuby cameo in the show's fifth season

Those who've binged the series' pot-boiling fifth season, of course, know that this cameo never happened. No, Burr didn't tap out of his Better Call Saul appearance because of unexpected professional commitments. Per a 2019 appearance on The Rich Eisen Show, the comedian explained a far more personal reason kept his Kuby reprisal from happening: "I was supposed to be on it [Better Call Saul], and unfortunately I had somebody who was dying, and I knew if I did it, I was going to miss. I had to visit him, I had to say goodbye."  

While it's a bummer that Burr wasn't able to Kuby-up for Better Call Saul, one has to admire that sort of dedication to dying friend.

While Burr has parlayed his Breaking Bad breakout into memorable appearances in projects like The Mandalorian, it's safe to say his biggest fans will be devastated if he never returns as Kuby. However, with one more season of Better Call Saul on the horizon, it's likely Kuby might still make his way into Saul Goodman's rapidly unfolding tragedy, if only because Burr continues to hold Vince Gilligan in the highest esteem. As he told Eisen, "The whole thing sucked. Because Vince Gilligan is the reason why I have an acting career."
