Nathan Fielder is the hottest man in comedy. His new show 'The Rehearsal' premiered on HBO last month and many fans are falling in love with his unique sense of humor for the first time. But if you've been following his light-hearted hijinks since the days of 'Nathan For You' you know he has long been the master of awkwardness.

And in all this time, there is only one clip of him breaking character. And the man who accomplished this is none other than the pee-drinking grandpa he met while running a gas rebate scheme that asked buyers to hike up a mountain in order to cash in their rebates.

After a long night spent camping out with three strangers, Nathan returns to the gas station to report on the success of his deal. Only things didn't go as planned when he brought up drinking pee. We don't want to say more, do yourselves a favor and grab whoever is near, because they're going to want to see this too.
