He makes elaborate plans for a perfect date, but things keep going wrong; Archie almost collides with people while skiing, so he seeks out a more remote spot and promptly runs into a tree.; When a roast is missing, Jughead weighs Hot Dog and finds he's five pounds heavier.; Jughead is alway first in line for lunch.; Val's cousin Roy tried to play the harmonica and swallowed it.; Jughead makes fun of Hot Dog when he hides under the bed during a thunderstorm, but then sees Archie is under the bed, too.
