Let's see this is quite a trick

[svetlana14]

On YouTube, in "Useful Expression - Live English Lesson", (https://www.youtube.com/watch?v=rgXKcJqybZY), at 1:03:17, I am struggling to understand the words after "Let's see this is quite a trick". Can you please to help me.

The "y" is mine.

She's wrong to say All means the same. She needs to sort her English out first.
