Have vendor take you out to lunch.

Walk into bosses office and regurgitate the lunch onto their desk.

Profit?

Take long enough and you can just shit on the boss’s desk, slap down the paper, and be mad at their ungrateful attitude for bringing back lunch.

Take a picture of the shit and add it to the expense report. Make sure you notate that you did not keep the gift and instead rescinded ownership to your boss.
