I actually think this is why the original trilogy works best. It’s very comedic but there’s not a ton of in your face jokes or puns or one liners.

Obviously there’s the odd delivery of weird lines you mentioned. But lines like “who’s scruffy looking?” Or “laugh it up fuzz ball” or even the way yoda feigns being an old senile creature to test Luke’s patience, these are all unintentionally funny. For example, who’s scruffy looking fits the solo character perfectly as he’s very image obsessed, very suave. When he calls chewie a fuzz ball it makes sense that that would be an insult you would pull out of thin air. Yoda being a weird crazy old guy also fits the bill as he’s intentionally doing it to see if Luke will grow impatient and angry, signs that he could be destined for the dark side like his father.

The new sequel trilogy misses the point entirely and that’s why the comedy seems so off in comparison. Lots of little one liners and stuff that don’t work like Finn saying “let’s go chrome dome”. Or when every character one after the other goes “stormtroopers can fly now!?!? They can fly now? They fly now!?” (Btw, storm troopers and clone troopers have always had jet packs in the other cannon media so it makes no sense that they wouldn’t know this. Especially Finn who was a trooper hinself). It’s also why yoda laughing like a maniac when the tree burns feels out of place. Yoda wouldn’t behave that way. He’s reverting to that crazy old man mentality which doesn’t make sense as that was only a ruse to test luke.
