Neil deGrasse Tyson is like everyone's second dad who happens to know a lot about science.
But he's still just as embarrassing.
In a video from National Geographic, the scientist explains what it would take to have sex in space. And things get super S&M real fast.
"If you want to sort of get together [and] stay together, you need something to, like, keep you together during all the normal body movements that would characterize having sex in space," Tyson says.
"So yeah, just bring a lot of leather belts to keep things strapped down and you'll be just fine."
Neil gets even more awkward at the end of the video.
Just stop, Science Dad. Just stop.
