Hahaha! That was actually funny!
Well, I could almost guess the punchline, but was pleasantly surprised. Audio was perfect as was the mouth sync and overall pace/ timing of the movie. Really too short, but this is your second movie submission, and it looks miles better than your last one (as far as a finished product.... first one looked very promising).
It wasn't a plain plane, just a one gag diddy that got in and out before anyone could cry foul. Good work!
This was sick and the animation was okay.
