Nerd for a Day is episode 4 of season 3 of Full House.


When Jesse learns that Stephanie has been joining her classmates in making fun of another child, he takes up the responsibility of encouraging his young niece to apologise and change her behaviour. She goes along with it to obey her uncle, but when Walter Berman (a.k.a. "Duckface") believes that Stephanie may have romantic feelings for him, she resents Jesse's involvement in the situation-until one little incident teaches Stephanie how much it hurts to be the target of teasing.

D.J. selects Michelle as her subject for a unique school assignment, and Joey temporarily steps in for Becky as Danny's co-host on Wake Up, San Francisco.
