This comic makes no sense and presents no joke. It’s just a drawing and some words that convey a meaningless scenario that makes no attempt at word play or observation.
Now if the caption was like “Frank was displeased to discover some Nag-weed growing in his garden” that would be a (very lame) joke but as it is now it’s just complete trash.
It’s a word play on “invasive”
Invasive plants are undesirable plants that can take over your garden, and someone who asks overly personal questions is also being invasive.
While I agree that the joke is not very good, invasive plants are a thing and prying uncomfortably into a stranger’s personal life is considered invasive, so it definitely has some sense.
This was the intended joke. But when was the last time you called a person invasive? Maybe it’s a dialect thing, but I’ve never heard that used about a person. Nosy, nagging, annoying, that’s what I use.
I hear it all the time. If someone asks a question that’s over the line, it’s too invasive.
