Joel has many opportunities to use his knowledge of the future to his personal advantage. He attempts to invest in Intel stock, and palms off 1990's pop music hits as his own; he sings Green Day's Good Riddance (Time of Your Life) at school, and turns in Nirvana's Smells Like Teen Spirit for a poetry assignment. He also saves his parents marriage by preventing an affair his mom has with his art teacher.
Do Over's premise invites intellectual speculation about what a man could accomplish if he had a chance to "do it all over again." Many an adult laments "if only I knew then what I know now." But the show focuses mostly on comedy. Pop culture references are thrown in frequently, and should be especially amusing for those who were in high school at the same time as the show's characters.
