A person who sniffs carrots.
The fact that Prince Charles could be seen on videotape sniffing these carrots raises the question of why he felt the need to behave in such a manner in the first place. The fact that he was caught on television doing it also raises the question of whether or not he did it intentionally. The event was captured on camera for record-keeping purposes.
Why did he think it was necessary for him to act in such a manner? The fact that he was caught on camera engaging in the behaviour further raises the question of why he would engage in conduct of this nature. The abrupt and unexpected appearance in front of everyone of a member of the royal family caught everyone off guard, and the scenario caused everyone to be taken aback.
