Why is it funny to say Giri played the Evans Gambit? At 0:55 in this video, Youtuber agadmator claims Anish Giri played the Evans Gambit in the Italian Game:

[fen ""]
[Black "Anish Giri"]
[White "Kirill Alekseenko"]
[Event "Candidates 2020 (Joke Line)"]

1. e4 e5 2. Nf3 Nc6 3. Bc4 Bc5 4. b4


It becomes clear thereafter that agadmator was joking, as he immediately smiles, says "No, he didn't", and continues with the actual line. 

However, I don't have the background to understand what makes the humour transparent here. 


Is this joke referencing an amusing history or reputation of this line?
Is it just such an obviously bad move that no one can take it seriously on face value? If so, why? 


I'm discounting the explanation he just made an error in his annotations because of the deliberate way he looks at the camera when he announces this, but I'll accept an argument for any interesting lines that spring from this position.
The joke is based on the perception of Giri as a very solid, "drawish" player. There always seems to be one top player who is the butt of such jokes. It used to be Leko, nowadays it's Giri.

Take a look at this reddit thread for example or this chess24 April's fool.

The swashbuckling Evan's is the last opening Giri would ever choose to play, or so the jokester suggests.
