This is a great design by Kase. Lightbulb head has a question mark thought bubble. Like all the creative power went into making the head look cool, but now the inspiration for ideas is not there. In essence the plug is pulled and the I Have No Idea man sits on the edge of the abyss.
Get this I Have No Idea T Shirt from Design By Humans because you will be the coolest person in your town while wearing it.
