No , no one made a mistake . That would suggest that whoever made the joke didn ' t know how intelligent design is actually defined . The reality is that whoever made the image most definitely knew how intelligent design is defined , but also knew that if you only take the words literally and don ' t apply external context , then they ' d mean simply what they say design that ' s intelligent . The person who made the joke took advantage of semantics , and comedians do it to make jokes all of the time . This isn ' t to say that I think the joke is funny . I don ' t think it ' s funny at all , but hey , I ' m not gonna judge anyone for finding it funny , because humor is subjective . <| sep |> 6 v cutoff for 2 , 9 v cutoff for 3 batteries .
