Penny

Penny is Socko's sister and a business woman who makes shirts with crazy, cool, random comments on them. She once was mentioned in one of Carly's blogs on iCarly.com.

Unlike most members of Socko's family, her name isn't a pun due to her occupation. What she does is sew a penny on to every shirt she makes (Penny T's). She remains unseen like all other members of the family except for Rob, Freight Dog, Bernie, and Dr. Paxil.

Also, one should note that some of the shirts that Penny makes are sometimes quotes by the iCarly gang themselves, one being one that Spencer was wearing, in which it said, "Pump Up the Fruit!." It was a quote said by Sam in "iCarly Saves TV." Also Sam wore a Penny T which said: "Church Pants" which is a quote by Freddie in iStakeout.
