I read a review on Funi I think that the animation in Ping Pong is reminded of Beavis and Butt-Head.. and honestly, there was this part in the OP(which is awesome btw) that did make me think of it. Mainly the hand-drawn squiggly style and dem short shorts. Plus Akuma does resemble Beavis in a way... so one day I traced B&B's headbanging gif
I added Smile in because Peco always needs a Smile(and the sake of full childhood friends roaster), and as you can see I referenced Daria.
On a Mike Judge related note, anyone watching Silicon Valley?
