Damn, but Bill Gates is out of touch when it comes to what ordinary people spend on groceries.

Appearing on The Ellen DeGeneres Show, he first discussed how he became a billionaire before moving onto a guessing game.

With five common grocery store staples lined up in front of him, he was asked to guess their cost. Kind of like The Price is Right.

Well, it didn’t take long to realise that Gates actually has no idea, reports TIME:

And while Gates definitely has the capacity for developing software, when it came to guesstimating how much the average person forks over for snacks and household goods, he was seriously challenged, going so far as to initially postulate that a box of pizza rolls would set you back a whopping $22 (spoiler alert: they’re only $8.98, according to DeGeneres).

Watch the full clip below:

He’s quite great, though, isn’t he?

Of course, with all that being said, Gates does use his considerable wealth to help others. He and wife Melinda pledged to give away $41,3 billion (R483 billion) to help others through the Bill & Melinda Gates Foundation, focusing on global health, education, and ending poverty.

So there’s that.

But how can you end global poverty when you think everything costs more than it does?
