It's clear that Bill Gates does not do the Grocery Shopping in his household.

According to CNBC, on Wednesday, February 21, the billionaire philanthropist and founder of Microsoft Bill Gates made his debut on "The Ellen DeGeneres Show."

'The Ellen DeGeneres Show'

In his segment on "The Ellen DeGeneres Show," Bill Gates and host of the show Ellen DeGeneres discussed many things, including his foundation, the Bill and Melinda Gates Foundation, and the trampoline room that Gates has in his house.

Ellen even got Bill Gates to play a Price Is Right-like game, where he has to guess the prices of various grocery items. And if he guessed at least three of the five prices within one dollar of the actual price, every audience member would receive a prize.

The grocery items that Ellen had Gates guess the prices of were Rice-a-roni, Tide Pods, floss, Totino's pizza rolls and T.G.I. Friday's spinach and artichoke dip.

Here are Bill Gates' answers compared with the correct answers: Rice-a-roni (his answer: $5, compared to $1); Tide Pods (his answer: $10, compared to $19.97); Dental floss (his answer: $4, compared to $3.78); Totino's pizza rolls (his answer: $8, compared to $8.98); T.G.I. Friday's spinach and artichoke dip (his answer: $4, compared to $3.66).

After some help from the audience, he was able to adjust his answers and ended up guessing three of the five prices correctly, and sent the audience home with a chance to return in December for one of DeGeneres' Twelve Days of Christmas Giveaways.

Gates admitted to Ellen that the last time he had set foot in a supermarket was "a long time ago." So maybe we should cut him a little slack.

Bill Gates' philanthropy

While he may not be in touch with what regular consumers pay at the grocery store, Bill Gates fights inequality worldwide. Born in 1955, the founder of the largest software company, Microsoft, has worked full-time along with his wife, Melinda, at the Bill and Melinda Gates Foundation since 2014, when he stepped down from his position as chairman at Microsoft. The foundation spends well over $4 billion every year to help people in many ways, such as distributing vaccines and improving education.

Along with his foundation, he announced in 2017 that he was investing $50 million into the Dementia Discovery Fund, and would soon donate another $50 million toward start-up research for Alzheimer's, a personal matter for Gates, who has seen the effects in his own family.
