My favorite, Peter the Great, was quite a prankster with wicked sense of humor. When he saw his nobbles dressed in oldfashioned outfits, wearing long beards and gathering on the squares of Moscow to conceive a revolt against him ( as he believed ), he charged cannons of this kind with steamed turneps and beets and fired upon conspirators. Crowds were dying from laughters watching nobbles running away and painted in orange and maroon colours. As you know, beets colour is tough to remove quickly, so Peter requested nobbles to report to him for council right after "execution". Nobbles had no choice, but shave their maroon beards off to stand before him without losing their dignity... Those old good times...
