You have much to learn, Grasshopper

One of those old kung fu movie lines that's just fun to say to newbies.

"Master, why is it that you deny me the holy root password?"
"You still have much to learn, Grasshopper."

Actually, it's a line from the old Kung Fu TV series, in which David Carradine a half-caste Chinese-American Shaolin monk wandered, mostly bare-footed around the American West with a walking stick and a bamboo flute having flashbacks.
