If you were too busy enjoying the weekend by spending it outside, you missed an epic live TV stunt Sunday on Discovery Channel's "Skywire" special.
Tightrope walker Nik Wallenda made all our stomachs turn by being the first person to tightrope walk over the Grand Canyon.
Yeah, prepare to feel nauseous!
According to a press release, this was the highest tightrope walk ever attempted by the so-called "King of the High Wire" -- as he tiptoed 1,500 feet over the Little Colorado River.
The entire event aired live ... so, thankfully, he didn't fall off!
He finished the walk in just under 23 minutes -- and even ran on the wire for the last few steps.
Check out the ridiculous video above and more crazy photos below.
