You can't help but love Don Knotts. When I was growing up, knowing he was on a show or a movie made the decision for me what I'd be doing that evening. You felt for his bumbling, stuttering, nervous, twitchy characters. He looked and played the part so well. This was a character actor who truly knew his niche. These are just some of the classics he was known for. RIP, Don Knotts, you were my first crush.
