Literally Blown Away

Recently overheard in a speech:

“And when they heard the band, they were literally blown away.”

Possible explanations:

1) A tornado touched down at the exact moment the band started playing.

2) The band had super amps set way loud, like Marty McFly did in the opening of “Back to the Future.”

3) Dynamite was attached to the audience’s seats, and the band played slower than 50 mph.

4) The speaker does not know what the word “literally” means.

Your suggestions?

Just my thoughts,
