Sit up animation is about a simple rainy day but not simply. At one animation company, there is a guy walking into the office to continue his work after the coffee break. He sits on the comfy chair. During, he is sitting and sipping the coffee. He trys to adjustment the height of the chair. Suddenly, the chair gets trouble with abnormal level so he attempts to get down to the ground gentlely by pushing the stick controller. Unfortunately, the controller slips out of the chair. He quickly glimpses to the ladder that placed beside the bookcase. He thinks that is the best idea to get down safely. He moves the chair quickly by pushing his body and it tends to work greatly in this way so he keeps pushing and pushing. The chair is getting closer and closer but lastly, he uses too much energy on pushing that cause the chair goes over the target and crashes the printer at the end.
