But I think the comic also worked because the punchline "I am scared of oblivion", much like "Christ, what an asshole," is a great universal punchline.
It works for everything!
Let me show you a few examples and I think you'll see what I'm talking about:
Original: Garfield
Original: Marmaduke
Original: Dinosaur Comics
Original: Cathy
Original: George Takei's facebook page
Original: Peanuts
Original: Buttersafe
You are welcome to send me more, especially if you feel like it!
OKAY BYE!
