Best Character Impersonations?

[Mirage]

I'm looking to become very good at impersonating a few different movie or TV show characters. I'm trying to brainstorm some of the instantly recognizable ones. I plan to become quite good at a few at a time, and then move on to do more when I finish on the first few.

Any and all ideas are welcome.

I can do a fairly good Sean Connery, especially ordering Taco Bell food.

I can do the voice of Fozzie the Bear. How about Nicolas Cage? He's a pretty good actor.

I have found the Holy Grail of impersonations:

I think I am going to go for doing something like this.

I can do several of the voices in there already as well as some additional ones that are even harder to do...

Several of those won't be hard to learn either.
