Homer Hadley is a baseball player depicted in the 1988 Sesame Street book Bert's New Collection. Although he does not appear in person, Hadley does grace a baseball card, which Farley gives to Betty Lou (since he had a double).
Homer Hadley's player number is 3, and he appears to be lefthanded. Outside of that, however, it's unclear which team Hadley plays for, what his stats are, or even what position (although the presence of a glove and ball on the card imply either pitcher or catcher). One fact is self-evident: Hadley sports an impressive moustache.
