People asked Elon Musk some very bizarre questions at the SpaceX Mars event

Turns out, the prospect of sending people to Mars elicits some pretty strange questions, statements, requests ... and even smooches.

On Tuesday, SpaceX founder Elon Musk unveiled the company's plans to send humans to the Red Planet in a highly anticipated speech at the International Astronautical Congress (IAC) in Mexico.

Then came the Q&A segment.

Musk spent about an hour and a half discussing SpaceX's strategy to fund and execute human colonies on Mars — and, certainly, several attendees asked him about that. But a few had more personal inquiries: one person wanted to pass a comic book, The Future of Fusion, to Musk onstage, and another asked if she could kiss Musk "on behalf of the ladies."

And the fun didn't stop there. In what was clearly a poorly timed pitch, someone looking to produce a Funny Or Die video asked Musk if he'd use math to ID the "most expendable" person (and thus the most appropriate passenger for a one-way Mars trip) on Earth. He then suggested that person was actor Michael Cera.

But the question that took the cake was from a recent Burning Man attendee, who wondered aloud whether Mars would have functional toilets or whether, like Burning Man, it would be a "dusty, waterless shitstorm." (It likely wouldn't be, said Musk, as there is ice on Mars.)

While Musk might not have loved being asked about Mars poop, it was certainly enthralling for the internet.
