The upper school brought Spirit Week to a rousing finish on Friday with the much-anticipated spirit rally held at Davis Field. As always, the hilariously entertaining skits from each upper school class were the primary draw.

Following a performance by the junior varsity dance squad (who performed a dazzling routine to the themes from “Pokemon” and “Kim Possible”), grade 9 students took the field with their spin on “Winnie the Pooh,” featuring a dance number that paid tribute to a number of Michael Jackson hits.

All four classes then participated in a game of “Human Etch-A-Sketch,” in which groups of students created scenes such as a school bus, tea party and merry-go-round. The seniors, having the most experience in spirit events, won the game.

Grade 10 then took the field for their own skit, which was nonetheless entertaining despite some unfortunate technical difficulties.

For their skit, several grade 11 students dressed up as the cast of Scooby Doo, who piled into their “Mystery Machine” van to solve another case. The Harker cheerleaders followed, performing an energetic and complex series of moves, ending with a human pyramid.

This year’s relay event had students running while using hula hoops and trying to snag donuts with their hands behind their backs. Not surprisingly, the relay ended with each one of the class deans receiving a pie to the face.

The seniors took the field for the final skit of the rally, in which they played characters from “The Magic School Bus,” with Andrew Irvine, chemistry teacher, playing the part of Ms. Frizzle and taking the students on a journey to observe Harker’s amazing senior class.

The rally ended with the student-favorite scream-off, which was won by the juniors. As a joke, the class of 2011 decided to merely pantomime the act of screaming while staying completely silent. After the upper school classes had their turns, the Eagle Buddies gave a spirited scream of their own to bring the rally to a close.
