Trundling on is his only option. Actually it's not even an option. It's his only setting.
All lolcows are like this, if they weren't, they wouldn't be the way they are. It's like saying this apple taste like an apple. They're not just incapable of acting otherwise, it's an ontological impossibility that they do. Results don't matter, inputs don't matter, they can't make choices. They're gravitationally compelled to proceed on the path they're on.
And Greer is the epitome of a lolcow. He's like the Terminator, but instead of killing, it's just acting retarded.
Listen, and understand! That lolcow is out there. It can't be bargained with. It can't be reasoned with. It doesn't feel pity, or remorse, or fear! And it absolutely will not stop, ever, until you are bored.
