The code is clearly wrong:

execute(say(), "Hello");

This passes the return value of say() to execute. However, you want to pass the function, so use execute(say, "Hello"); and in that function use someFunction() to execute it.

Even though it probably/hopefully doesn't matter anymore, the code does work in Firefox - it alerts undefined since say() is executed before execute() runs. The same thing happens in Chrome - however, it uses an empty alert box instead of showing the string undefined since apparently chrome (or at least its developer console) has a global variable ?name? defined by default which is an empty string.
