Young
What do you call a very young bee?
A babe-bee.
Yesterday
If yesterday was today - today would be yesterday.
Yawning
Of course, I'm listening to you; don't you see me yawning?
Young
When I was young, I had a lot of spots and pimples. One day, I fell asleep in a library. I woke up, and a blind man was reading my face.
Yesterday
Fred: Did you meet your wife at the airport yesterday?
Joe: No, I met her at a dance about ten years ago.
Yawning
Keep talking. I always yawn when I'm really interested.
