How can a Java programmer play a trick on a C++ programmer?

Question

Java

I work as a Java programmer, I didn't study C++, I immediately learned to program in Java.
Here a corporate party is brewing and you need to come up with jokes from Java programmers about C ++ programmers, they will have similar jokes but vice versa!)
Who knows what? What can be said or read about C++ programmers that would be funny?)

Answer 1

No need to joke with him, his forehead is covered in bruises from blows with a rake.
