Nope, Yoda is ALWAYS silent but deadly! I was wondering if any Yorkies did fart out loud! Hahahah..
I think he's used to his own farts now, he doesn't mind them. I think when he was a baby, he'd turn around and go, who's that stinking up my room? But now it doesn't faze him at all. Of course, when Mommy and Daddy fart, Yoda always gets the blame now.
