I learned:

Lizard men can somehow chew and swallow food without getting it all over their eyes (which are inside their mouths).

Impaling an emperor of the universe instantaneously causes his attack on Earth to end, no matter what external forces he has employed for the task.

Being impaled on spikes makes your eyes and tongue stick way out.

Ming's guards never check for rocket cycles prior to abandoning people on soon-to-be-destroyed floating kingdoms.

The male-to-female ratio of most kingdoms of Mongo is roughly the same as an Alaskan bar.

Somewhere in Ming's fortress is a hangar with dozens of guards and commanders just sitting around waiting for someone to send them into action if rocket cycles ever come close and then run away.

The easiest way to win an alien friend for life is to whip him a whole bunch and then help him up.

Reciting the formulas of Einstein and a song by the Beatles will instantly negate the effects of any brainwashing.

Agents who fake a brainwashing will psychically know once they are no longer under surveillance.

One can be a hero and save the universe (necessitating a celebratory song in his honor) without doing anything particularly heroic aside from playing a scrimmage of football, pretending to get bitten by a woodbeast, winning a whip fight, kicking one (1) soldier off a war rocket wing, blowing up a helpless navigator with a hand grenade, and kamikazeing into a palace.
