Student: "Ms. D, if you hold in your fart, does it come out as a burp?"
Me: "I don't think that's how it works."
Student: "I think so! And if it's true, does the burp have poop particles in it?"
Me: (Trying really hard not to completely crack up because they were super serious.) "Guys I don't think there are poop particles in your burps."
Student: "Are you sure because sometimes my burps taste like poop."
