7. 'I Just Called to Say I Love You'
Not a lot of people remember the 1984 Gene Wilder sex comedy The Woman in Red, but everyone remembers "I Just Called to Say I Love You" from the soundtrack. The song shot to Number One on the Hot 100 and even won an Academy Award for best song, beating out Ray Parker Junior's "Ghostbusters." Stevie even sang a bit of the song with the cast of The Cosby Show when he guested on the program a few years later. You see, Theo and Denise got into a minor car accident with Stevie. He invited the whole family into the studio, and of course, they all broke into song fairly quickly. It's one of the all-time great episodes.
