Prince William is having a cheeky time.

The Prince of Wales has always been calm and polite, but in recent months he has been enjoying seeing how far he can go with his thoughtful little remarks.

His latest antics came during an appearance with Princess Kate on BBC Radio 1's "Going Home" program, hosted by Jordan North and Vic Hope.

In one segment, the royal couple took cute questions submitted by viewers.

"Is this pretty or does it belong to your family?" William began ominously. William began ominously (via People).

"They said I shouldn't say eggplant, so I have to pick something else. The one with the eyes up and down and the mouth sticking out. Something a little crazy."

Yes, the future king was referring to a pictograph called "zany face," according to Emojipedia. This is as interesting a royal fact as the idea that the eggplant might actually be the King's favorite (although I suppose the King was just enjoying a bit of a shock).

"Mine would probably be the heart emoji and then the crying emoji," Kate said. 'A good laugh when things go wrong.'

This comes after another hilarious joke William made last week.

To mark the beginning of Black History Month in England, William and Kate took a picture with some of the people they met that day. Suddenly, the prince joked, "Who's pinching my ass?" and everyone burst into laughter.

Oh, William, what am I going to do with you?
