I think this is supposed to be interpreted as '“lol gas = dino juice so a time traveler can get free gas” but I initially read it as “Finally I have located the birthplace of the first sentient hominid. It is time to undo the destruction of mankind before it even begins. For a touch of irony, I will immolate them with the very poison with which they would have devastated the Earth.”
I saw it as neither. I thought his gas-powered time machine had run out of fuel, so he’s walking to the nearest gas station (the joke being that there won’t be a gas station in this era, so he’s trapped).
honestly that sounds most likely to be what Larson intended lol
I interpreted it as the time traveler using the Time Machine to fuel his car / machine because it’s gone in the future.
Hey! He got lucky!
He can just grab a dinosaur and make it pee in his can before it gets into the dirt and sinks down to where it has to be drilled for!
He was walking to get gas. Because he was out of it.
I know what’s wrong with it.
