What two things does Kenny say are wrong with him get teased at school

Kenny says he gets teased because there are two things wrong with him: the first issue is that he is extremely smart, so all the teachers love him and treat him differently. (When he was in second grade, a teacher once had him read passages of Langston Hughes's work to Byron's fifth grade class.) The second issue is Kenny's lazy eye. However, Byron taught him a way to avoid having people look at his eye: Kenny just has to look at people sideways when they talk to him.
