For the longest time, the answer was almost always "The commercials!"

The question:  What's your favorite part of the Superbowl (unless of course, the Bills are in it. But we'll leave that one alone for now)?

But over the past couple years, companies have started "leaking" their multi-million dollar ads weeks before the game.  I'm not sure what the point of that is, but I wanted to pass along a few of them to you, just in case you'd like a preview!

Here's Mr. Clean's ad, featuring a sexy, animated Mr. Clean, mopping.  At least they gave him a nice tush! :)

Here's a pretty ruthless ad for Mercedes, produced by the guys behind "Fargo", "The Big Lebowski", and "No Country for Old Men"...

This one's pretty fun, too.  Ravens quarterback Joe Flacco talks about how to avoid being a "party pooper"....
