This strip is obviously referencing the lyrics to the classic Fats Domino song "Blueberry Hill"

But the lyrics go:
I found my thrill
On Blueberry Hill
...I remember the first time I saw this comic, sometime in the nineties, I think. My dad explained it to me very similarly to how you did here.
There was a similar comic, which currently I can't find; I don't even remember if it was Far Side, but the art style in my head matches. The comic in question features two dogs hopping around a hillside covered in blueberries with one declaring to the other "you were right! This is thrilling!" I read them far enough apart in time that I think my dad had to explain it to me again.
In trying to find the latter comic, I discovered that Putin performed a cover of the song in 2010. Odd. Wiki page mentioning this: https://en.m.wikipedia.org/wiki/Blueberry_Hill
As I like to say when movie makes a modern day celebrity or TV reference, "hahaaaaaa that's a pop culture reference that will definitely stand the test of time."
Still funny, though.
