I saw that the article mentioned 45 bonus skecthes. At first, I mistakenly thought that it said 45 bonus features.
Lets see. We know that it will have appearances by James Earl Jones (the article pretty much confirmed that the sketch where he counted to 10 will be included), Johnny Cash (the article pretty much says that Nasty Dan will be on there), Jesse Jackson, and Jackie Roberts, and it will have Rubber Duckie, I Love Trash, C is For Cookie, Pinball Number Count (not sure which one, or if its more then one, or if its all of them), the King of 8, The Alligator King, and the Ladybug Picnic. That is 11 sketches (22, if all of the Pinball Number Count skits are going to be included). That leaves 34 more skits to be included outside of the episodes.
I am going to make a list of 34 skits that I hope to see included as bonus skits (and of course I don't know what episodes will be included, so if any of the following skits listed are going to be included, then thats a bonus in itself)
1. The Banana Sketch part 1
2. The Banana Sketch part 2

I realize that some of those skits are from later than season 5, but I think the Pinball Number Coutn sketches are from season 8.
