This is one hilarious drinking game!

Neil Patrick Harris stops by "The Meredith Vieira Show" on Thursday, where the two play a rousing game of "Drink or Dish."

The rules are simple: the players are asked a series of potentially embarrassing questions and they can either answer the question and "dish" about it or take a shot of white wine.

When NPH asks the talk show host about losing her virginity and her least favorite cohost on "The View," Meredith is driven to drink!
