scary smart 

A demonstrated level of superior mental intelligence, accompanied by a high I.Q., beyond that which people of "average" intelligence find comfortable or can understand, often to such a greater degree that it leaves them feeling intimidated or even somewhat frightened.

There is "smart," there is "really smart," and there is "scary smart"—so smart that you are glad the person uses their mind for good and not to rule the planet for their own enrichment. ~Professor David Tulloch, Rutgers University

SCART 

Although producing a better quality image than an RF connection, the connector design requires the plug to be perfectly aligned over the socket before it can be inserted at all. This makes it particurlaly difficult to insert a SCART connector into a concealed socket, such as one located on the back of a TV. This fundamental design flaw in allowing a successful "male" to "female" connection raises the question as to whether the SCART designers had ever experienced the ease with which an erect penis slides into a vagina.

Watching someone on their knees struggling to plug in a SCART lead for what seems like several hours is an extremely miserable experience.
