I'm late to the party, but the given example reminded me... if I may combine a few conversations from my childhood and convert to a syllogism:

A) Humans can do anything they set their mind to. (Proof: god was afraid of what humans could accomplish and scrambled their language in genesis.) (me, excited: What about time machines? Hmmmm... ok:) A') Humans can probably do anything they set their mind to. B) Thought is faster than light. (Proof: I can think about being on Mars instantaneously, even though it takes light 30+ minutes to get there). C) Therefore, faster than light travel is probably possible.

I've developed a theory that there are two kinds of people: those who model reality in their heads, and those who don't even bother to try. I'm not sure how to describe the sensation, it's not exactly physical, but hearing logic that poor hurts.
