Favorite intentional anti-climaxes?

As the title states, what're some examples of a moment, reveal, or whatever being intentionally anti-climatic, and it actually works?

JoJo part 4 has Kira's death. He's been cornered by the Morioh Warriors, and Jotaro has beaten him within an inch of his life. What does him in? An ambulance backing up and accidentally crushing his head. A brutal, but fitting death for someone who tried his hardest to never stand out.

The reveal of the Administrator's plan and goals in issue 7 of the TF2 comics. Previous comics have built up that her ambitions with the Australium are potentially apocalyptic in scope. And building on that, we had to wait over 7 years to finally get an answer to our questions. Turns out, she was using the Australium to keep Zepheniah Mann alive so he can watch the endless squabble between his two loser sons that she specifically engineered to be incompetent. And this entire process has been going on for around 150 years. What's the reason behind her blistering hatred? Well, according to the cover images, he or another member of the Mann family was presumably responsible for the deaths of her family, but it's been so long that she's forgotten most of the exact details.
