Cartoon Characters Stuck in Real Life

Cartoon characters have their own universe and their own dimension (it used two be two dimensional world but lately computer graphics and animation tend to be 3D more and more often). What would happen if by some bizarre twist of faith these fictional animated characters popped out and appeared in real life. I guess, our life would suddenly become much more interesting and loony :) . Check out how Astrix, the Simpsons, Shrek, Tarzan and many others would handle themselves in these situation.
