LOL! That Abbott & Costello routine is of course a classic. I seem to remember posting a video of it here some time ago in another thread. But it's so nutty it's worth a repost, especially as it's fairly short:

There are alien-believers who say that the aliens landed their space craft in ancient Egypt and then employed some kind of power ray to lift, move, and place massive stones in place to build the pyramids. (So hopefully no exploitation of Egyptian serfs occurred).
That's doubtless science fiction.
ALTHOUGH, according to one episode of the TV program "Ancient Aliens" there is actually scientific evidence that, at least under laboratory conditions, it seems that sound waves of the right frequency and strength can indeed levitate small items such as ping-pong balls.
Of course, even if true, the amount of sound power needed to move a 10-ton block of stone would presumably be stupifyingly colossal compared to that needed to move a ping-pong ball.
But here's a short clip (5:15) from "Ancient Aliens" about
the supposed power of stone-moving-sound-power, with a reference at 4:30 of its suggested ancient use in building the pyramids:
Maybe it put a heck of a humming sound in the air when it was employed, as giant stone blocks hit by sound waves suddenly lifted up, and flew through the air to appropriate positions on the growing pyramid?

At least it may be theoretically possible, though still highly unlikely.
