I want this to be awesome but their anti-troll technology appears to be "hang at 'analyzing image...' for 20 minutes."

No, no, wait. It did it. Their test image was "appears to be a man holding a bat in a field." Okay, Captionbot...

"I seem to be under the weather right now. Try again later :("

Yeah, captionbot, that image makes me sick, too. Nice job.
