he is being funny and silly by standing there with a straight face on every vid he does the same look on his face and just stand there looking crazy at the camera I think its funny example if you want to make your BF GF BFF your kid ect funny or slip through drink across the room by laughing sit there look at them with a blink expression on your face your mouth open or something else silly like that and watch Its pretty Fking funny
The reason he looks so upset and never smiles is because of losers treating content creators bad he was smiling in a video with his kids and because someone was a rude loser and said he looked like a pedo he now never smiles in his videos again
