Custom: You come over with my roommate. I'm on the bed studying. We recognize each other from a class we both have. I go back to studying and keep farting, and despite how much I try to cover it up, it becomes more than obvious. I admit it was me. You don't mind, thankfully! You ask me about a time someone farted in class. I come clean about that fart too, and briefly talk about the embarrassing incident.
