(Debuted July 27, 1985, Peaked #58, 12 Weeks on the Chart)
Comedian Billy Crystal spent a single season on NBC-TV's Saturday Night Live and developed a character during his time on the show. Based on real-life actor Fernando Lamas (who died in 1982), Crystal used two phrases Lamas once used on an appearance on Johnny Carson's show: "It's better to look good than to feel good" and "You look marvelous." Both of those phrases are in the lyrics of Crystal's novelty recording "You Look Marvelous."
The bit was a sensation. Not only did Crystal do the bit several times on SNL and on other NBC-related broadcasts (like the 1985 All-Star game's pre-game show, where he "interviewed" Yankees owner George Steinbrenner), he also incorporated the character into his own stand-up act. It was also included in his 1985 LP Mahvelous! which contained the single.
As with many fads, the "Fernando" bit ran its course fairly quickly.
