Singular or ...?

A third grade school teacher was trying to
explain to her class the difference between
singular and plural.

She said, "What is it if one woman looks out
a window?"

Little Charlotte said, "Singular."

"Very good," said the teacher. "What is it if
three women are looking out of a window?"

Little Johnny mumbled just loud enough for
all to hear, "A wh0rehouse."
