Follow the bouncing ball
The situation: Down 20-7 with 10:45 left in the third quarter, the Bills face a third-and-12 situation at their own 49-yard line.
Things got a bit nutty when ...Ryan Fitzpatrick's pass intended for Brad Smith ricochets off the knee of a Dolphins defender, pops into the air and is picked off by Reshad Jones. It was just one of a number of unfortunate events to strike down the Bills, who have lost seven consecutive games.
Amazing feet
Things got a bit nutty when ...Eli Manning passes to running back Ahmad Bradshaw, who allows the ball to bounce off his hands, but is fortunate enough to kick the ball back to where he could catch it as he falls to the turf. The Giants capitalize on their fortune, getting a 40-yard field goal from Lawrence Tynes two plays later to trim the Redskins' lead to 17-3 before intermission.
That's snow fun
The situation: Up 23-13 with a bit less than six minutes left in the game, the Dolphins have a first-and-10 at their own 24-yard line.
Things got a bit nutty when ...Reggie Bush storms through the Bills defense for a 76-yard touchdown run that ices the win for Miami. Bush ends the run with a slide through the end zone. Teammate Brandon Marshall joins in on the fun, and the pigskin party is greeted with a yellow flag. But who can blame the Southern California kid for wanting to have a little fun in the snow? It turned out to be a banner day for Bush, who rushed for a career-high 203 yards in the win.
How's that for entertainment?
Things got a bit nutty when ... It's all fun and games until a monkey rides a dog around the field. Fans in attendance and TV viewers at home all get to revel in this rare sight. This is the sort of behavior we would expect from the Titans, who gave fans a cheerleader being eaten by a mascot and T-Rac battling the Galactic Empire last season. It'll be tough for Denver to top Sunday's spectacle.
The Panther-rooski
Things got a bit nutty when ... The Panthers dig deep, deep, deep ... deep into the playbook for this doozy. The Texans defense seems thoroughly confused when the Panthers lined up for the trick play, and were completely unprepared for Cam Newton to slip the ball under the backside of Richie Brockel, who promptly ran around the left side of the line for a touchdown.
