Urkel resorts to despearate measures to win a date with Laura by camping out on the Winslows' roof, even though a big blizzard is fast approaching Chicago. Meanwhile, Richie meets new next door neighbor Gwendolyn.

Lonely and depressed after breaking up with Ted, Laura grants Urkel a few bittersweet hours of bliss as her valentine; Gwendolyn charms Richie with "yucky goo-goo stuff"; and Harriette and Carl search for admirable qualities in each other.
