Fregley is a “weird kid” who lives near Greg’s house. Greg thinks Fregley is weird because he makes strange comments, seems oddly interested in gross things, and uses a “secret language,” like shouting “Juice!” when he wants to go to the bathroom. He is the only student light enough to be in Greg’s weight class during the wrestling unit in physical education class, so Greg has to wrestle him every day—which he finds excruciatingly embarrassing. When Greg is fighting with Rowley, Greg tries to become best friends with Fregley to make Rowley jealous. Greg immediately regrets his decision when, during a sleepover, Fregley goes on a sugar high and begins chasing him around with a booger on his finger.
