Battle of the Codemonkeys

I'm entering in the registrations for our summer reading program right now, and if there is a duplicate registration, the most technical database error message possible pops up. Of course my 14 year old volunteer had no idea what a key is, or a "System ArgumentException, or why he should "review the stacktrace" to find an error. Can't it just say "sorry, this person is already in the database"?

What I love is his reponse to all this. After I literally decoded the message, he said: "oh, it's written by code monkeys!"

Yeah, I thought those were cute and cuddly until it came out of his mouth, but what a great insult for a fourteen year old to use!
