Cheer Up!

Read a "funny" story from an airplane magazine I get.

A pilot and his co-pilot were almost to their destination; the pilot had noticed his co-pilot had been in the dumps through the long flight and hadn't said much of anything even when the pilot had tried to engage him in conversation.

Approaching the airport, the pilot gave the command to lower their landing gear and the co-pilot complied without a word. Almost to the ground, the pilot said to the co-pilot:

"Cheer up!"

The co-pilot retracted the landing gear, thinking the pilot had said "Gear up!"
