Greg Universe is a rich man now, but in his mind he was always rich as long as he had his son Steven and his music. Greg shares that wisdom with Steven and Pearl in the fan-favorite Steven Universe musical episode "Mr. Greg," commemorated on this charming T-shirt. As Greg says, "Singing a song don't cost nothin'." This shirt, however, does cost somethin', but hanging out with Steven and his family is priceless.
