Nerd for a Day

Plot:

Stephanie and the rest of her class get detention for calling classmate Walter "Duck Face." Uncle Jesse says being nice to people is important and makes her call Walter to apologize. Unfortunately, Walter takes this to mean Stephanie is his girlfriend, and she suggests being his "secret girlfriend" instead of rejecting him outright and hurting his feelings. The next day when her friends come over to work on a school project, Walter shows up just before everyone else and they find him holding her hand.
