Well, that all depends on what kinds of clouds we're talking about. If it's a Lakitu's cloud, you might see a Lakitu in it. If you mean the clouds of fog that show up in my town during the winter, you'll likely see a car crashed into another car. But you must mean the clouds that drift slowly across the sky.
Sadly, I haven't seen single clouds in any particular shape lately. The weather suddenly !warped from cloudy-all-day cold to cloudless heat. Therefore, I'll report in sometime later this week. Not a bad topic, by the way.
