Shin Megami Tensei Nocturne - Jinn Animations

Incredibly subtle reference to obscure indie film maker Walt Disney and his cult classic adaptation of the Arabian fairy tale.
Specifically, the jawdrop is taken directly from the film, while the big windup punch seems like a more generic cartoon thing which I couldn't find a better example of (googling "inflation arm gag" did not, in fact, lead to clips of classic cartoons).

Jaw-droppingly good animation.
