New Trope Proposal related to the Beatles' A Hard Day's Night

So, I'd like to propose a Bad Acting trope: "Who Knows Hahahahaha?"

Here's the context from A Hard Day's Night:

Grandfather: Hello. John: He can talk then, can't he? Paul: 'Course he can talk. He's a human being, isn't he? Ringo: Well, if he's your grandfather, who knows? Hahahahaha!

So, when Ringo delivers that line, since he and the other Beatles weren't much actors (although he'd prove a better actor than the other Beatles in the future), it sounds like he's asking "who knows hahahahaha?" Therefore, this trope would be for when an actor's mis-delivery of a line makes it sound like they're saying something different than they were supposed to say. In this case when Ringo says "who knows" and then laughs "Hahahahaha," his less-than-stellar delivery makes him sound like he's asking if anybody knows "hahahahaha" when he wasn't. How's that for a trope? Enough examples from works to support the trope idea?
