I have a teenage student who takes my Skype lessons. Usually we talk directly without a headset, but one day, he was wearing one. He said it was because his house was under renovation and noisy. I thought it natural, and began the lesson, though the sound was not very clear. Around half way of the lesson, he grinned at me and asked, "Do you know what this is?", pointing at the microphone just in front of his mouth. Before I answered, he took off what I thought was the mike from the headset and showed it to me. It was......a spoon for parfait!!!
