Computer generated images are like the foam sets of the present era: 20 years from now, people are going to laugh their asses off at the fact that this stuff looked even remotely real to us.
That's why, as we've mentioned before, there are still filmmakers doing special effects the old-fashioned way -- even if the results are so impressive that you'd never know it's not CGI.
There's CGI in Cracked's new Adventures in Jedi School mini-series, but the humor is all a practical effect.
Inception -- The Dream Collapsing
Inception is one of those movies that could have easily gotten away with doing every single special effect in CGI, because it's full of so many insane moments that we assume half the things in it are computer generated anyway (for example, there's no evidence that Ken Watanabe is a real person).

Water: Leonardo DiCaprio's Natural Enemy Since 1997.
They had huge water cannons hiding outside the windows, firing somewhere between 3,000 and 4,000 gallons into the set as DiCaprio stood there, soaking wet.
"Finally, I can pee in public and no one will know!"
Don't think DiCaprio got to have all the fun, though -- if there's one scene that screams "CGI," that would be the iconic hallway fight scene where Joseph Gordon-Levitt climbs up walls and runs through the ceiling as if gravity had taken a break:
