Archie Kelly is one of Greg's awkward school friends who is also cast as a singing tree in the school's production of The Wizard of Oz. But as the night progresses, Archie gets in on the act with Greg in attacking Patty Farrell. After that, he constantly gets harassed in the hall and gets called "Bubby" due to the fact that during the play, Greg was called Bubby by Manny and he was able to "deflect" the embarrassment over to Archie.
