It's football season on "Catch It/Keep It", as three armchair quarterbacks decide to get up off the couch and try their hand at pulling an end run against Mike's latest destructive force: a few blow torches, a dummy run, and some blasts from a water hose. Catch It/Keep It Action... it's FAN-tastic!

Our three rookies...

- MARVIN B. SMITH, JR.: architect, carpenter, teacher.
- DEMETRIOS "D" KALLIOS: carpenter, fabricator, inventor, former college linebacker.
- JAMES CERASANI: metal fabricator, carpenter, entrepreneur, jack-of-all-trades

And the prize for a successful touchdown? VIP tickets to the 2010 NFL Pro Bowl in South Florida, complete with accommodations, and $100 from NFLShop.com.

This week's MOD is a 15-yard-dash of destruction involving 250-pound "linebackers" (55 gallon drums), 2000-degree flamethrowers, motorized spinning arms to knock the ball loose, and a high-pressure wall of water. And the ball itself is no ordinary game ball... It's been submerged into liquid nitrogen. They have to get a mannequin in NFL garb (which we'll refer to as "the player").

Remember, you cannot mess with, touch, or alter the MOD or the player.

Forty-eight hours... starting now! Good luck!

In their first hour, they decide on guiding the player through a track using a coffin-like rig, thus going UNDER the MOD.

40 HOURS BEFORE KICK OFF

So far, their idea is still that.. an idea. On paper. And no sooner than that realization is made than we have...

TEST #1: Mike's Water Pressure Test... Mike thinks that they're underestimating the full force, all 1200 psi of the water cannons. One of those hoses can rend asunder a trophy case. Two of those hoses can send a clunker moving. They're starting to think about deflecting the water. D & James will construct a shield to do just that out of sheet metal.

Now that their deflector's finished, it's time to go back into their rails.

Meanwhile, Mike is making his own solution... a hallway blocking everything.

23 HOURS BEFORE KICK OFF

The challengers still have to figure out how to get the player to safely drop into their coffin.  While they're doing that, Zach & Mike are having fun with liquid nitrogen.

20 HOURS BEFORE KICK OFF

The team starts to assemble their solution... but they still don't know how to get the player into the coffin. Mike notices that that could be problematic. Zach says we hear a lot of "need to" and we need to hear a lot of "done".

D senses a need to take charge and get the team to work.

18 HOURS BEFORE KICK OFF

The team uses ancient Egyptian technology to move the coffin across the field. But we're still missing the X factor: getting the player into the coffin.

TEST #2: Mike's Ball Drop Test. The team isn't really thinking about protecting the football. It's important to know what they're up against in terms of the liquid nitrogen. A melon... breaks. On a piece of insulating foam... protected.

The game clock is running out... The team press on as normal, testing their coffin track out and adding a blocking mechanism for the drums. Now that it works, how are we going to get the player into the coffin? They decide... a simple hangman's hook will do it. They test it... FAIL.

5 HOURS BEFORE KICK OFF

... and they're no closer to success than they were last night. D sets up a block of concrete in front of the barrels, while Zach comes in. It's game day.. you need game jerseys.

D decides that they need something to block the third barrel. Enter... the car. Marvin's not having any of that. He steals the keys to the forklift. "No more key.. no more D."

3 HOURS BEFORE KICK OFF

That third barrel is problem #1. James goes with a tripod system to stop the barrel from descending. As for the football player... they think they have it ready. All they need to do is set everything up.

3 MINUTES BEFORE KICK OFF

And time to wrap it all up. Remember, the players get one down and one down only. The MOD is triggered in five... four... three... two... one... and away we go. Fire up the RB!

James drives the guy into the coffin... but before the player gets into the coffin, the football is FUMBLED for a loss. In the end, it was James' error that would cost them the Pro Bowl.

But the game is not over yet. Mike sets up his solution, and if it fails, then they still win. Hut hut hike! Mike guides the player through his tunnel... and he runs it in for a touchdown. Touchdown Mike Senese.

So no win today, but next week's another challenge and another prize to be won. Remember, if they catch it, they keep it.
