Now this may explain the whole thing ...

You see, there were these two sheep herders flying the herd to a new farm. Suddenly, the engine fails and the plane begins to fall quickly to the ground.

SH1: Quick! Grab a parachute and jump!

SH2: What about the sheep ?!?

SH1: Fuck the sheep !!!!

SH2: (pause) Do you think we have time?

The guy just forgot to mention the part about the plane.
