Clark Cobb is an evangelical Christian who is the head of the Christian Businessmen's Association and the owner of Cobb's Family Hardware. His first appearance is Wall of Youth.
He is a man, though well behaving and a gentleman at first, is opportunistic and money driven underneath. He is not hesitant to put his need of business over his Christian values, which he frequently does, and merely follows his religion more as a means of entitlement to "okay" his money making schemes "in the name of the Lord".
Beavis and Butt-head ran into him a few times in the series, and even more times in the comics. However, he rarely recognized them.
He has a sock puppet named Socko in which he mostly carries around. In Ensucklopedia, it is mentioned that he has a different looking sock puppet called Socko 2. Known fans of Socko include Stewart Stevenson and Dean Zunker.
In Whorehouse, he campaigns against the abortion clinic by yelling "Whores! Fornicators!" This lead the boys think this was an opportunity to get laid. Socko is absent in this episode.
His character is similar to Mr. Garrison from South Park, because of how the two look and the fact they both have hand puppets.
It is also implied in Ensucklopedia that he became interested in hardware because Jesus Christ was a carpenter.
