That pose has to be some sort of running gag right I've seen a lot of it recently
It reminds me of the Cactuar from Final Fantasy, but I feel like it's probably some sort of stock pose that is even older; maybe originating from a 'pedestrian crossing' street sign or something? Would be interesting to find out the history on it!
Wow that brings back memories omg. You're probably right that its based off something else like pedestrian crossing or even the emergency exit sign.
