The soul of "Caveman in the Airport" was how it made the viewer think. The idea "what would I do if I saw a caveman in the airport" was forced into the viewers mind. Being confronted with the idea of coming across an anachronism is the thought provoking hook.
Now all you've done is place him in modern settings with a nonsensical performance. Confusion is not the main appeal. The idea you want to trigger is "what if I came across this Caveman, what would I do?". So he needs to be in scenarios familiar to the average viewer, performing activities that people see on a regular basis.
Here's a free idea, what if the Caveman was a grocery store employee stocking shelves as a customer asks him for help finding an item, he responds with a mildly shocked "Hello", as if he wasn't expecting anyone to talk to him. The interaction can quickly segue into the Caveman saying the GEIOCO mobile app promotion while he searches for the item on his phone. Grocery store employees often use phones as scanners/searching devices to stock shelves, so this would be a recognizable & logical everyday scenario to put the Caveman into which leaves you with the feeling "what if I experienced this scenario?" The phenomenon of the Caveman exemplifies a niche that's not well explored, and yall have the resources to explore that niche, and have the background of establishing it in our minds in the first place! Please don't let that go to waste, honestly I've only written all this because I think it's a very entertaining idea that would be profitable if correctly executed. But these recent caveman videos are huge disappointments imo. I hope these words find the right people :)
