“Earnestness is stupidity sent to college.”
“Stupid people go to college but"smart people own them"....”
“Many wise words are spoken in jest, but they don't compare with the number of stupid words spoken in earnest.”
“Every year, many, many stupid people graduate from college. And if they can do it, so can you.”
“What is earnest is not always true; on the contrary, error is often more earnest than truth.”
“It is always interesting to see people in dead earnest, from whatever cause, and earthquakes make everybody earnest.”
