I submit, to you, the funniest 2.5 minutes of all time. After finally finding this on YouTube, my kids and I have watched it repeatedly.
It is always funny. It never stops being funny. And, like all good and funny things, it only gets funnier with repetition. Driving it into the ground is a mere beginning.
Unsurprisingly, it's Monty Python. (George Harrison famously said there was no successor to the Beatles -- save for Monty Python.) But what merits dismay: No one, anywhere, it seems, includes "Rival Documentaries" in their lists of favorite Python sketches. The sketch is so funny that you can read this unfunny buildup, and STILL... it's funny.
If you do not appreciate the non-stop genius of this, it's not my fault. Respectfully -- and I submit this with humility borne of love -- it's because you're stupid.
