Someday You'll Find Her, Charlie Brown (1981)

After Charlie Brown spots a girl briefly shown in a sports event broadcasting, he is smitten enough to go in search of her with the help of Linus. Unfortunately in his search, he has his usual amount of luck. As Charlie Brown is watching a football game, he spots a girl in the stands that he immediately attaches himself to. When the game ends, he is desperate to find her, so he enlists Linus to help him and, because of his absolute nervousness, to do the talking for him. However, that move could wind up spelling doom for the love-starved Charlie Brown once they finally find her.
