"I invented the cordless extension cord"

This quote by Steven Wright is a funny take on the concept of an extension cable. By stating he invented the cordless extension cable, he is suggesting that it is difficult to have a cordless extension cord. This is due to the fact that an extension cord is a cord that is utilized to extend the reach of an electrical outlet, and by definition, it must have a cord. For that reason, the quote is a play on words, and is implied to be taken as a joke. It is a smart way of explaining the absurdity of the idea of a cordless extension cable. The quote is a reminder to not take life too seriously, and to delight in the humor in daily circumstances.
