It was a conflict of book smarts versus common sense when MIT student Star Simpson entered the Logan International Airport wearing a shirt with a circuit board and a 9V battery attached. To make matters worse, she was holding a lump of playdough in her hands.

Star Simpson, 19, was wearing a black hooded sweatshirt and approached an airport employee in Terminal C at 8 a.m. to inquire about an incoming flight from Oakland, according to Major Scott Pare of the State Police. She was holding a lump of what looked like putty in her hands. The employee asked about the plastic circuit board on her chest, and Simpson walked away without responding, Pare said.

In the words of Homer Simpson, “I am so smart. S – M – R – T. Smart.”
