Ah, Cisco Ramon, the one character that regularly turns up with the coolest lines, the coolest inventions, the coolest mannerisms, and the coolest fashion sense. And its the latter that came into play in Potential Energy. For a large part of the episode, Cisco can be seen strutting around in a T-shirt that features a white bear, a black bear and the brilliant caption of Lets make a panda. Bravo, Mr. Ramon. Bravo.
