Movie: Walk Hard: The Dewey Cox Story (2007)

Though it's not exactly uproarious, director Jake Kasdan's 2007 send-up of conventional biopics, Walk Hard: The Dewey Cox Story (co-written with Judd Apatow), has its fair share of memorable jokes and visual gags, chief of which is the pun-filled song "Let's Duet."

Crooned in collaboration by Dewey Cox (John C. Reilly) and Darlene Madison (Jenna Fischer in person, Angela Correa on vocals), it's a ridiculous track that's made funny due to how straightforward it's delivered by all involved. Dewey sings, "In my dreams, you're blowing meā€¦some kisses." Later, Darlene belts out, "You can always come in my backdoor." Romance, by way of Apatowian perversion.
