Ever since you met Bucky you had been obsessed with his arm. Mostly cause it was funny to use in pranks. Often he would wake up with magnets on his arm or you gluing google eyes to it. It was annoying to him especially this time. Even this time you can admit you might've gone too far-but you were on a mission. A mission to steal his arm and one day while he was napping you somehow found yourself dislodging it and immediately taking off and bolting with it the minute you realized you took off his arm just praying that he didn't actually kill you when he woke up.

Unfortunately for you... "WHERE IS MY ARM!?"
