A. The country singer may have been on the way to a recording session.
You only need one nail to hang the painting.
I can maintain polite conversation.
Where there is a fork in the road.
Sing* Hello from the other side!
When the terrorists asked for anything cheaper than one-way.
They are four ways you can lose your house!
A. "One can read, one can write and one to keep an eye on the two intellectuals."
One to put in the new one, and two to sing about how good the old one was.
Two. One to screw in the lightbulb and another to sing about all the good times they had with the lightbulb.
