Explanation
The Joke
A person shouts "No! Stop!" at someone using a time machine. They warn: "You can't time travel! Whatever you change will have unforeseen consequences for the present!" The time traveler, undeterred, asks "Do you like the dinosaurs?" The other person hesitantly replies "I... uh... I guess?" The time traveler declares "And so..." and the final panel reveals the result: the dinosaurs are now still alive, and they are enormous, with Earth visible in the background and a small rocket fleeing the scene. Someone exclaims "Wooooo!" -- the time traveler is apparently thrilled with the outcome.
The comic plays on the classic time travel trope of the "butterfly effect," where small changes in the past have massive unintended consequences. The time traveler's casual question about whether the other person "likes" dinosaurs turns out to be a setup for a catastrophically literal interpretation -- rather than, say, bringing back a pet dinosaur, the traveler has prevented the extinction event entirely, resulting in dinosaurs that have continued to evolve and grow for 65 million additional years, now dwarfing the planet itself.
The Humor
The humor comes from the absurd escalation. The warning about "unforeseen consequences" leads the reader to expect subtle, complex ripple effects through history. Instead, the consequence is hilariously obvious and maximally catastrophic: planet-sized dinosaurs. The time traveler's gleeful "Wooooo!" as they rocket away from the chaos they have created adds to the comedy -- they are not horrified by the consequences at all, but delighted. It parodies the reckless optimism of anyone who thinks they can use godlike power responsibly while clearly having the judgment of a child at a zoo.
