Robert Rodriguez's "The Black Mamba", starring Kobe Bryant.

That was pretty cool. I went skim the wiki entry on black mambas after the video, it's pretty funny:

...

Cape file snakes, hawks, and the Boston Celtics are all also predators of black mambas.<sup id="cite_ref-Haagner_1-2" class="reference">[2]</sup>
