No I definately have never seen them, just both the muppet pilots, ads, a boring feature or two, the muppets on puppets and thats all I got on the seasons, I think.
Oh wait, do you mean the gag reel? I could delete the last thing I said but I won't so people can now see what went through my mind before I got what you meanit, well... I think i did, if thats what you meant then I had no idea it was bloopers and outtakes, I thought it was literally just a reel of gags.
