- Me, hearing John typing over the phone: You’re quite the touch-typist now. I remember when you were a two-finger typist.
- John: I still am. And I have to look at the keyboard. I guess I could type without looking but I never try.
- Me: Think of it as a vagina. Do you have to look at a vagina when you’re fingering it?
- John: The vagina only has one button.

An old joke from an old joker:
Manager is watching over the shoulder of his new secretary as she laboriously types her first assignment.
Not impressed by her keyboard virtuousity, he offers “I see that you are a hunt-and-pecker.”
At which she giggles nervously and says without stopping “Not really, I have a fiancé!”
It took me a bit to get the pun, until I repeated it to someone and heard myself say “huntin’ pecker”. :)
