"So, I really would like to know who made this thing!" Liz muttered as the two of them made their way out of the room. Steven was in front and Liz was bringing up the rear, studying the device she had in her hands.

"We've got no way of knowing!" Steven sighed.

Liz then smirked. "If nothing else it will make an interesting paperweight" she laughed.

"Woah...look!" Liz then said, as she grabbed Steven's arm to spin him around. The doorway that had appeared in the wall quickly disappeared, and Liz's cabinet 'popped' back into existence. "This is so much like Warehouse 13!" she said, causing Steven to roll his eyes. "And don't you dare poke fun at my favorite TV shows!" she suddenly warned Steven, wagging a finger at him.

"Wouldn't even think of it!" Steven smirked, raising his hands in feigned surrender.

"Right...now what are we going to do with this thing?" Liz inquired, turning her attention back to the device. She ran her fingers along the underside of the 'ray gun' and accidentally hit a lever of some sort. A brilliant, incandescent beam shot out of the device and struck Steven...who was stood more or less alongside Liz. "What the..." Liz began to say, before they were both momentarily blinded and immobilized.

"...hell was that?" Liz then finished her sentence, as things seemed to return to normal.

"I'm...not sure!" a disorientated Steven responded, shaking his head. He then realized that he was holding the device, and he raised it up in front of him. "When did you give me this?" he asked, rather puzzled.

Liz and Steven's heads had been switched, and were now on each other's bodies.
