Bill Gates on "Ellen."

• Microsoft cofounder Bill Gates failed miserably at guessing the price of common grocery items in a quiz game on "Ellen" Wednesday.
• He thought a $20 container of Tide Pods cost $4 and gave a wildly exorbitant guess at the cost of a bag of Totino's Pizza Rolls.
• He nailed the price of dental floss.

It may come as no surprise that Bill Gates, the second richest person in the world, has no clue what groceries cost. 

The billionaire Microsoft cofounder appeared on "Ellen" Wednesday and had a tough time guessing the prices of common consumer items in a quiz game.

"We're going to test your knowledge of some everyday items that you get at the supermarket," Ellen DeGeneres said to Gates. "When was the last time that you've been at a supermarket?"

"A long time ago," Gates replied. 

In the game, Gates guessed that $1 Rice-a-Roni cost $5. He thought a large container of Tide Pods cost $4, but it costs $19.97. He also gave a wildly exorbitant guess at the cost of a bag of Totino's Pizza Rolls ($22).

"This is my best chance, at this one," Gates said, as the game turned to guessing the price of a dental floss container.

After professing that he "absolutely" flosses, Gates nailed the price of floss at $4.
