Clarissa Explains It All

This was a smart, entertaining, clever, original, and funny show. The characters were lovable and it was a fun show growing up with. However, as I retrospect I begin to question the show. First off how come at the time I found Melissa Joan Hart so attractive and now I don't. And how come Sam always came in through the window?! Why didn't he just come in through the door like a normal person? Something was going on between Sam and Clarissa because why would he come in through the window?! Makes you wonder doesn't it! I guess Clarissa didn't necessarily explain it all!
