To keep this somewhat low-key on the gross scale, I am invisioning a contraption somewhat related to the game of Mousetrap to get the pee infused into the burrito.
This also takes me back to an apt i used to live in in Chicago. There was a burrito joint around the corner that got shut down by the health inspector- big green fluorescent sign in the door window and they were closed for like a week and a half. Then they reopened. My roommate (extra-naive, she was) went back after they reopened, and took her boyfriend at the time, not telling him that it had been closed by the health inspector. He was one of my good Polish friends (a later roommate himself), and once they broke up, I told him.
Me: "Let's get a burrito."
Him: "Cool, let's go to that place around the corner."
Me: "Dood, didn't you know that burrito place was closed down for like a week?"
Him: "What?"
Me: "Yeah, there was this big green sign in the window- didn't you see it?"
Him: "What?"
Me: "(her name) didn't tell you?"
Him: "What?"
