Actually, to be honest, it hasn't hurt.

I've had a couple of recent instances where this has occured:
"You remind me of that guy from, uh, that movie Superbad. What's his name?"
"... Jonah Hill?" (my face then looks like this:

)
"Oh, I think it's kind of cute."
That said, I'd like to think my rather blunt, forward nature makes more of an impact than any resemblance to Jonah Hill. I bet he is a pussy in real-life. I'm that guy that you dare to do something and I do it. Or the guy that gets you to do something you wouldn't have done otherwise. Totally antagonistic.
