The Office - Jim's Gain

It was like any other day at dunder-mifflin paper company, everyone is working hard and goofing off. Jim Halpert went and gave Pam, his wife, a hug and kiss then told her that he is going for lunch.
After grabbing his lunch, he realized that he really needed to piss, so he left his lunch on the table. While he was gone dwight came in, grabbed the soda in Jim's lunch and replaced it with a soda infused with a powerful appetite enhancer.
As soon as Dwight left the lunch room, Jim left the men's room, sat down at the table and started eating.
