A man was walking down the road one morning and he met his friend.
M: Good morning.
Oh, you are wearing a glove on one hand, and none on the other hand.
Did you know?
F: Oh, yes, I heard the weather forecast this morning.
M: Weather forecast?
F: Yes, the weather forecaster said on the one hand it might be fine
but on the other hand, there might be some rain.
