I'm quite sure we can't use this construction in English, but I'd say that mr Bob is a "gigantic teacher", thinking about how efficient he is and how amazing his classes are.

This lesson so calm for some reasons.. may be gigantic things tend to calm down people a little.

Certainly a gigantic lesson as always! Thank you, Bob.

I USE YOUR CHANNEL TO LEARN ENGLISH AND THE SUBTITLES ARE VERY IMPORTANT FOR ME.

Thank u❤ Mr Bob.

Today is my first day to learn English, I look forward to say English fluently some days

Hello dear teacher Bob! 🖐️🤠 Your lectures on various subjects are very helpful. Thank you for making the difference. 💯♥️🤩👍 Have a great Sunday! 👋😎💐🌹💙

I haven't been on a cruise ship yet either. I need to include this in my bucket list.⛴ 🙋🏼‍♀️😃

Thanks Bob, Let's take care of our gigantic and beautiful planet.

Cảm ơn Anh nhiều lắm luôn thank you so much my dear friend

What a cool t-shirt you are wearing today! It suits you well.

I am in this exact moment (04:16 a.m) in a sentry box where I work watching this video and learn more about english. Thanks a lot, teacher Bob. Hugs from São Paulo - Brazil ❤

Thanks teacher Bob 🌹

Thanks a lot for this video, dear teacher Bob! I wonder if Jen's friend on whose flowers the gigantic ballon fell, received any compensation? Was it just an accident? The farmer's work, in my opinion, cannot be measyred with money. Groving plants is a very long and expensive process. I applaud Jen and her angelic patience! I wish you a great Sunday and have a gigantic harvest every year! 💐

Hi, Bob, this is Mary, I am one month new fans here, thanks a lot for your wonderful vedios. Which helps a lot especially when we need to use English in our daily life. Most of the time in our text book, we got what we learned, but still we do not how to say a lot of things. Thanks again.

Thanks for Bob , I'm in the east 03:56 AM 😊
