I believe that this is a Milk-chan (Oh! Super Milk-chan or something) parody. I recall the President (of everything) waving his hand like this a few times when he's talking to Milk about... eh. If it's not it, feel free to remove the tags.
I don't think so, Gimeul. After the horrible memories subsided thanks to you reminding me of that stupid show, I distinctly recall that the President would slam his fist down on his desk repeatedly, not in the air.
