The reason why canine flatulence is so terrible is that you don't know it's coming. At least when you do it personally, you can feel it coming and have a sec to brace yourself properly most of the time.
PS: I've been working on some poetry since some people liked my sexual haiku. What do you think of this: ''Dog gas . . . comes from Dog ass. . . I am the walrus.'' That's pretty good, isn't it? I mean, I don't think it's technically stealing from The Beatles. Mostly because I plan on pronouncing it Wal-RASS, just to make it rhyme. Well, you think about it and drop me a line when you've thought it through.
