Marcia tearfully frets "I'm ugly, ugly, ugly!" over her new braces. Then her date Alan Anthony (Mike Robertson) cancels, claiming that he must go out of town with his parents to visit a relative. Greg, Mike, and Alice attempt to arrange replacement dates, but a lack of coordination ruins the plan. Then just before the night of the dance, Alan arrives ... showing off his new braces (which he had fitted after an accident with his bicycle).
