Google spits out: "The product of the three numbers is 10,225 (65 * 20 * 8). The three numbers are 65, 20, and 8."
Whoa. Math is not AI's strong suit...
Bing spits out: "The solution to the three people in a circle puzzle is that all three people are wearing red hats."
Hats???
Same text was used for both prompts (all the text after 'For those curious the riddle is:' in the GP comment), so Bing just goes off the rails.
