...sure...
As an adjective, we know that sure means certain; without any doubt. However, in the spoken language — and not just the American variety — sure is also very commonly used in personal observations as an adverb to add emphasis and turn it into an exclamation. In other words, by using sure, you can take a plain statement like You look pretty today, and turn it into an exclamation:
[I have to say...] You sure look pretty today!
In this usage, sure gives your exclamation a nuance of «I just have to say,...!», especially when your observation comes out of nowhere because something — good or bad — just struck you, and you just feel you have to say something. So it can sometimes also express an element of surprise on the part of the speaker; a sudden realization; something you may not have noticed before.
But it can also refer to something that you've known for some time, but you were just prompted to comment on it now. In other words, it's very spontaneous. For instance in the example below, you've known for some time that you friend knows English, but hearing him on the phone just now prompted you to say something because you were so impressed. So instead of stating the plain fact, Your English is good, you say:
[I have to say...] Your English sure is good!
Since this sure turns any observation into an exclamation, it calls for a special intonation— a singsong quality that goes up and stays high, falling slightly towards the end. The word sure itself, always has a secondary stress, and the primary stress falls on another word after it. And it's always used after the subject and right before the predicate (verb phrase).

This sùre is an interesting bóok!
[To your girlfriend after she guilted you for forgetting her birthday]

This meme is funny because apparently, electricians don't normally clean up after themselves. So this is something tradespeople (other skilled workers on a construction site) will never say: «Wow, I HAVE TO SAY... I'm really impressed with how those electricians cleaned up after themselves!»
Note that using this structure has exactly the same meaning and nuance as exclamations starting with Man/God...! In other words, these are two ways of expressing the exact same nuance of something YOU JUST HAVE TO SAY, but with different words and very different intonations.
⦿ Mán/Gód, this is an interesting bòok
= This book sùre is ínteresting!
⦿ You may not be a professional chef, but mán can you còok!
[Picking a hotel room from a site]
This room has a pretty view.
[Stating a fact]
Your English is good.
[Speaking from experience]
Chinese is hard.
[Walking into the actual room]
⫸ This room sure has a pretty view.
[Having just overheard them on the phone]
⫸ Your English sure is good.
[30 minutes into your first Chinese lesson]
⫸ Chinese sure is hard!
In these three examples, the only difference between the first column and the second, is that the first contains statements of pure fact (with the corresponding intonation), and the second contains spontaneous exclamations with the nuance «I have to say...».
Additionally, the first and third examples express an element of surprise, discovery. In the second example, the speaker may be surprised if he's hearing you speak English for the first time. However, it's also possible that he's known for some time that you speak good English, but JUST HAD TO SAY something now, upon hearing you speak; as if he was just reminded of how well you speak it and had to comment.
