Neil Patrick Harris
Neil Patrick Harris has made an appearance in every Harold and Kumar film as a fictionalized version of himself. In the first, he plays a womanizer and drug suer, despite being an openly homosexual man in his everyday life. He was not publicly out when the first movie premiered, but the character came back as a womanizer in later films and said that coming out was just a way to meet more women. His real life partner played his drug dealer.
