Johnny Mercy has turned the tables on his giant stepdad. After shrinking his stepson to tiny size for three years, Richard Lennox finally developed a Grow Ray and returned Johnny to normal size, but Johnny grabbed the shrink ray and shrunk Richard to get back at him. Now, his tiny stepdad is at his Mercy's mercy. He makes the tiny man sniff his stinky socks and rub his disgusting feet, as he was made to do so many times himself when he was tiny. Who's the big man now, stepdad?
