What exactly did Jon Stewart say at that moment in the video?

If you think it's a good idea to rely on Google to improve your English, go right ahead with my blessings.

Good luck with that, as a native speaker of English might well say.

No, I don't think it must be a good idea. To me as a non native learner of English, it's an available option and reference when non native learners are not readily accessible to native speakers in their real life. Thanks for your perspective.

You seem to be misunderstanding what we're telling you. We're not saying it's ungrammatical. We're not saying that absolutely no one uses it. We're telling you that the more natural choice, in our experience, is "very helpful".

If you're going to take all our advice, test it out on Google (that well-known experienced English teacher and native speaker), and then challenge everything we tell you, you're going to find two things:
1. You won't learn much because you'll be spending your time arguing with us.
2. We'll become less enthusiastic about helping you.

By the way, in future, if you say that you've found examples of usage on Google, please provide links to a few of those examples.

I checked on google, and there are countless instances in which people say "greatly helpful".
Why so?

I Googled "glove romney marsh" and got 3,462,597 hits. Do you imagine that proves anything?

So did I and many are not native-speaker sites.
