You know how the whole business of farting is so amusing to even the most mature people? Well, apparently, it starts really early. Vir has found the humor in this smelly little joke and it's hilarious to watch. He farts, gets a mischievous and conspiratorial sort of grin on his face, and then just bursts out laughing at the sound he just produced. I guess the smell doesn't bother him just yet, so it's just pure happiness untempered by the not so pleasant byproduct of the funny sound! I guess it helps that his dad is who he is and his sense of humor is what it is...so at least we know where he's getting it from!
