In all seriousness, the person who got me hooked on musicals HATES them: My dad.
He brought home a video (yes, I'm dating myself here) of "The King and I" and I was maybe five or six. I was not happy because it was not the latest Disney film (which was checked out of the video store). Well, he said "You'll like this"-put it on, and I watched it on repeat pretty much until it was due at the video store. I couldn't stop watching it or being transported to that magical world. Well, soon after, I was asking for more of those movies (saw most of the R&H Collection by the time I was seven) and...the rest is history. (I came into the city with my parents, eventually just my mom, and saw my first few shows.)
To this day, I still remember my dad (who again, HATES musicals, because "in real life people don't just burst into song!") bringing home that movie and starting this passion for musical theater (although I enjoy plays as well).
Just goes to show that someone who detests musicals can indeed introduce someone to the genre.
