Dennis the Menace is the [[NamesTheSame name]] of two completely different and unrelated comic strips that both coincidentally debuted in March of 1951, one in the UK and one in the US. ''[[http://www.cracked.com/article_18788_the-5-most-mind-blowing-coincidences-all-time.html On the same day]]'', even. Both strips feature mischievous youngsters named Dennis, both of whom own a dog, and both of whom are BratsWithSlingshots. Weird, eh?
