I'm trying to come with abuse I can throw at him when he messes up, I have a couple:
1) Your web development skills are so poor, they have just been referred to a food bank.
2) Your code has so many bugs in it, green peace are protesting against it on grounds of cruelty.
3) Your code is so bloated that when it sits around the server it sits AROUND the server.
Feel free to add.
