The girl pasted over Tintin is Wednesday Addams, and she mistakenly refers to Captain Haddock as a commodore, so instead of Tintin saying "Captain, it's Wednesday," Haddock says "Wednesday, it's Captain."
The joke is it inverts the usual "what a week/but captain it's Wednesday" meme. Wednesday (the character) calls the captain Commodore (a title for someone in command of a group of ships, but lower rank than an admiral). The captain corrects Wednesday, saying he's just a captain.
In the original instance of this meme (no idea if it's like that in the comic as well) the captain says exhaustedly "What a week." And Tintin says "Captain, it's Wednesday!"
I've seen one case where people trying to make rage comics & wojaks "look better" by using ai. Like a techbro they are not getting the value of a meme is not high quality visual or professional visual, while in fact, shitty edits with noticable jpeg artifacts can make a meme funnier or ironic.
