Teach him Java J2EE, Spring, Struts 2, Hibernate, PL/SQL, and cure him of this blight immediately.  This is what I do daily and you don't want him to end up like me :-)<p>I kid, of course.  Probably the best thing to start with would be something like Perl, Python, or perhaps even Lua.  In fact, Lua might be something he could even use in the gaming industry later.  Whatever you do, don't introduce the poor kid to C# and DirectX :)<p>edit - on second thought, follow the advice of others and teach him guitar
