Shrek: "And you are going to be a father!"

A complete "mastool" kid calls me this evening (Name withheld to protect the guilty):
- "Hello, my name is ***. I'm a son of your teacher.."
- "Hmm, what teacher.....??"
- "No, I am a son of your father.."
- "What??????"
- "Oh, sorry, I am completely confused. I am a student of your dad".

(he wanted to get consulted on where to learn physics from)
