I ' ll take Dark Matter if you can wait 20 hours <| sep |> A lot of professors know tons of stuff but absolutely suck at teaching . So if I ' m learning basic history , I would take the fifth grad teacher . Why ? The teacher speaks to an audience where she must break down the concepts and explain them clearly . The professor is likey to skimp over concepts and just say do z , y , and z assuming you can figure out why . <| sep |> I found your big toe <| sep |> only 1 i can think of 2 <| sep |> this christmas , when opening your presents , please spare a thought for two dads and a small lebanese child who won ' t get anything . no santa claus , no turkey dinner , and no presents . if you can spare one billion pounds , we can save the people of the impoverished region of triforcia . thank you .
