In this episode, Mike is concerned about a blow torch being used so close to a cow's flatulence. However, contrary to popular belief, the high amounts of methane emitted from cows (and being blamed for global warming) does not come from a massive amount of flatulence. Rather, it comes from the burping of a cow. All ruminating animals (cows, sheep) burp high amounts of methane. One cow can burp 400 quarts of methane gas per day.
