hard to tell whats funnier, the video or the comments

I especially like the adolescent "Mine's bigger'n yours" catfights
about the composition of flatulence, none of which are anywhere near
right. For those interested, the largest single component is usually
nitrogen. You swallow air when you eat; most of the oxygen gets
involved in various biochemical processes, but the nitrogen just
trucks on through.

Then come free oxygen, CO2, methane, and sometimes a little free
hydrogen, in widely varying proportions. All the above are odorless,
so it falls to a richly varied array of esters, ketones and sulfides
to furnish the inimitable social character.
