There's really nobody out there who expertly makes use of social media for pranks better than Nathan Fielder. Two years ago Nathan had his Twitter followers asking their parents for drug money, and then there was that whole Dumb Starbucks business from earlier this year. Nathan's now trying to connect with his fans on Instagram, the only problem is an old man's boner keeps getting in the way. (Typical Instagram problem, am I right?)
It could happen to anybody really, but as Nathan told Conan "unfortunately there was a reflection in my sunglasses of my computer monitor" and Instagram had a problem with the porn reflection. Then it happened again... and again.
