From Homestar Runner Wiki
In phonetics, schwa refers to a short, unstressed and toneless vowel sound. Some examples of schwas in the English language are the 'a' in about, the 'i' in pencil, and the 'o' in eloquent. Visually, it is represented by an upside down 'e' (ə). References to this linguistic feature have occasionally surfaced in the Homestar Runner body of work.
