Earlier today, USC tweeted out a photo of Matt Barkley teaching a young Haitian how to make the universal sign for a touchdown. If you missed it, and it's likely you have, a bunch of USC football are down in Haiti on a pretty dang cool trip. But the photo will be our starting point here.

This got me thinking: What would other athletes plopped down in a place that had little knowledge of American football teach their new friends?

It can be somewhat serious things. For example, Desmond Howard:

Or less than serious things. For example, Pete Carroll's calling card:

A few starting points...

Paul Wulff teaching kids how to celebrate:

Jake Rodgers with the universal sign for metal ... or his pancake block celebration:

The proper way to react to a flag on the field.

Vincent Jackson with the proper touchdown signal

Or Pat Fitzgerald teaching youngsters how to call plays.

We can even involve referees!

These are a start. So pick a player or a few and tell us: What signature sign, signal or celebration would they teach someone who's getting their first introduction to football?
