It's certainly not impossibly heavy, but the android does make it look easier to heft than it actually is. He's about to turn back around to the machine when he seems to remember himself, tilting his head a fraction of an inch towards the doctor. "I am Data."

It's strange to be on a ship where he doesn't have the personnel files for every crewman in his memory banks, but hey, at least he remembered to introduce himself eventually.
