My friend George loves picking his in the car. He has fat fingers and we call it rooting, like what pigs do for food.
It reminds me of the scene in Seinfeld when he was scratching his nose, but got busted as it looked like he was picking it.
Even funnier was in Caddyshack when they bet if the Smails kid would pick his nose, and then bet if he would eat it. I know it’s gross, but my humor is sophomoric.
