OMG...the mysterious world of the NFL pile is revealed with one simple GIF.

Steelers' Cody Wallace went absolutely savage on Randy Starks of the Miami Dolphins.  Whether he was looking for snowballs or digging for gold, we're not quite sure.  One thing we are sure is that Starks was not feeling comfortable.  Check out the little leg quiver at the end.

I picture Starks making a sound much like a squealing pig.
