Hahaha, I was hoping something weird was gonna happen. You sure did deliver. It went on just long enough, it was really getting tedious. Loved how the compliment guy started stuttering before he burst. The delivery of the voice acting was kinda cheesy, I guess that's what it was supposed to be. I did like the body language. Was this maybe created as a bit of practice for that? The one-shot zoomed out nature of most of the movie really brought the punchline fully, and I think the restrained animaticy...animation worked with it, too. These kinds of people really are the most annoying. I know because I'm one of them sometimes. Maybe the breathing came a bit early when he was getting threatened, wouldn't he be kinda trying to hold his breath because he's afraid of the knife?
Simple but funny, keep it up!
