masturbating?

[gothamgirl]

today some guy told a joke that helen keller only masturbated with one so she could moan with the other [hand].

to everyone else it was very funny.

can anybody explain this one to me?

[skoobadooba]

she was deaf and blind..... the other hand was for sign language (moaning)

[gothamgirl]

well i knew that much.

...um.
Then what don't you understand?
In the joke she used one hand for masturbating, one hand for "spelling" out the moans.

[gothamgirl]

so we moan when we masturbate?

This is not a puberty related question.
