A bit of a spinoff, but if you were to choose your top five favorite episodes, what would they be? This is obviously not an easy choice, but I'd probably go:
1) The Haunted House - A fun, spooky episode that ended up being the premise for Don Knotts' The Ghost and Mr Chicken.
2) Three Wishes for Opie - Countess Van Talecki.
3) Back to Nature - Web footed, red crested lake loon.
4) Andy on Trial - Barney takes the stand to defend Andy after getting him into trouble. Don Knotts one dramatic scene on TAGS and he knocked it out of the park.
5) Mountain Wedding - Love all of the episodes with Ernest T. or the Darlings and this was the one that had them both including Ernest T's first appearance.
Way too many HM picks to include them all, but Barney's First Car, Citizens Arrest, Barney Joins the Choir, etc are just a few.
