Programmer Humor

WTF are you talking about? All I'm saying is that if you write code (that in the context of this discussion passes arguments to a method you didn't write, that may not be the type the author of the method expected someone to pass, but really, that's completely beside the point), you should, oh, I don't know, maybe test that it actually works, and maybe even (gasp) write some automated tests so that if anything changes that breaks the expected behavior, the team immediately knows about it and can make appropriate changes to fix it. You don't need a strongly typed language to do any of that. You just need to do your job.
