Pretty annoying
Well, the joke was pretty much like it said on the tin, annoying. Even when he gets stabbed, it wasn't that much of a relief.
Right, what needs to be worked on here? You've got a decent setup of the mouth sets that you want to use, but there seems to be an issue with the tweening in that the pieces need to move too far - perhaps a middle frame to tween to would help? That could help you to get the lip sync right, which would improve this flash no end. On top of that, will we ever see the annoying orange again, or will there just be a glass of OJ making these appalling jokes?
When it bleeds, the spurts of juice would die down a little and would probably splatter more, as in across the scenery and even over the hand - the dynamics of a bleed when the knife is in the wound is fantastically different to how it goes when the knife is removed. (The great stuff you can learn from forensics lectures)
