In response to earlier post saying that there was no season 5:
NONE of the episodes on the Season 5 set are on the Season 1&2 or Season 3&4 DVD sets. I now own seasons 1-5 on DVD, and I can attest that these episodes are NOT duplicates of other sets.
While most SBTB websites only have 4 seasons in their episode lists, it seems that there is inconsistency as to how the episodes are listed, and how they are divided into seasons.
These episodes (below) are on the Season 5 DVD set. They are NOT on the Seasons 1-4 DVD sets. (I got the episode numbers from a SBTB website episode list.)
62: The Fight, 63: Student-Teacher Week, 64: Screech's Spaghetti Sauce, 65: The New Girl, 66: The Bayside Triangle, 67: Teen-Line, 68: Masquerade Ball, 69: Day of Detention, 70: Wrestling with the Future, 71: Drinking and Driving, 72: Love Machine, 73: Class Rings, 74: Isn't it Romantic?, 75: The Will, 76: The Teacher's Strike, 77: Slater's Sister, 78: The Senior Prom, 79: The Video Yearbook, 81: Snow White and the Seven Dorks, 82: Earthquake, 83: Best Summer of My Life, 85: School Song, 86: The Time Capsule, 87: Graduation
Two episodes missing from this list (80: Screech's Birthday, and 84: Slater's Friend) were on disc 3 of the Season ONE DVDs.
So, this Season 5 set does NOT contain the same episodes as in other sets. Any true fan of the show can look over those episode titles, and will remember at least some of them (like "Teen Line") and recognize that they are NOT in the sets for Seasons 1 through 4.
While Cody gets an A+ for effort, the episode that he refers to in his review is not a senior class trip, but simply a "class trip." It is the first episode on the first disc from Season 3.
