Hi,
We knew about him in Portugal and the kids at school used to talk about him, although none of us had seen it, but we heard about it. I didn't think much of it, because grandpa was a nasty one on this ... he was a rather well known composer in Portugal, and when grandma would call up to say dinner is ready, he would come to the top of the stairs, let out a huge fart and then go back to his study!
And he used to tickle our feet with feathers, and to distract us, in the middle of it, he would fart ... and of course when grandma said anything, here came another one, and different too!
Never learned anything else about him. But my mom didn't like him much either! She was a momma's girl!
