A Lufthansa flight is over the Atlantic when there is a loud BANG! The plane shudders, and starts to go down. The pilot gets on the speaker and says, "Ladies und gentlemen. As you probably haffe noticed, we haffe lost all of our engines, und we are currently plummeting toward zee ocean!" Well, everyone on the plane starts screaming and carrying on. The pilot gets back on the speaker and says, "Ladies und gentlemen, haffe no fear! We at Lufthansa haffe prepared for just zuch an emergency. Listen carefully. Zoze of you who can swim, move to zee left zide of zee airplane. Zoze of you who cannot swim, move to zee right zide of zee airplane." So the passengers start trading places and moving around; swimmers on the left and non-swimmers on the right. After a minute or so the pilot gets back on the speaker. "Okay, ladies und gentlemen. In just a few minutes we vill plummet into zee ocean. Zoze of you on zee left zide of zee plane: as soon as we hit zee ocean, leave zee plane und swim avay as fast as you can. Zoze of you on zee right zide of zee plane: thank you for flying Lufthansa!"
