Why it worked
The humor in the video comes from the relatable stereotype of dads preferring certain types of drinks (in this case, beer) and the exaggerated reactions to less preferred options. The quick cuts and visual gags keep the viewer engaged.
Summary
The video shows a man reacting to different drinks presented to him. Initially, a blue drink and a chocolate milkshake are shown, to which he makes a disgusted face. Then, a variety of sodas appear, followed by beers, with his reaction changing to approval as the beers are shown.
