Here are 50 touchdowns that have left us with our jaws on the floor and wondering how did that just happen.

Kevin Cobb, of the Memphis Tigers, dropped some jaws with his flexibility and balance on this kick return. After the initial hit, most Tennessee players believe the play was dead, but Cobb knew it was not.

In a game between Memphis and Ole Miss, the Rebels dug deep into the playbook for the first play of the second quarter.

You have to watch the replay to watch this play unfold.

Cam Newton and the Auburn Tigers knew that a win in the SEC title game would secure their spot in the national championship game.

With the game still up in the air and seconds away from the half, Cam Newton killed the hopes of South Carolina.

After LSU had success with a fake field goal, other teams tried the same play.

Nebraska made an attempt at it against Colorado, and it went horribly wrong. Watch as Jimmy Smith reads this play perfectly.

While many teams have run their own version of the play called "Fumblerooski," Utah ran it to perfection and saw Jereme Brooks get into the end zone.

Everyone around college football had their jaws drop when Knowshon Moreno, hurdled a defender on a run. LaGarrette Blount took hurdling to the next level when he not only hurdled a defender but then took it in for a score.

Fast forward to 2:25 to see Blount finish off the Cowboys in the Holiday Bowl.

With the game still tied between these two top-10 teams, Cam Newton did what he did best in 2010, take over a game with a game changing play.

With under :30 remaining in the game and Texas facing a fourth down, Young answered the prayers of Texas fans around the nation.

With LSU just outside their own 20, Kentucky and its fans believed they had things wrapped up. The players had gone so far as to already administer the Gatorade bath only to watch this happen.

LSU was no stranger to last second Hail Mary's as they were the victim of one in the Capital One Bowl.

This was one of those moments in which Iowa fans went from screaming at Drew Tate out of frustration to screaming at him out of joy.

Boise State is the school that made the Statue of Liberty play famous, but in 2007, Oregon put their own twist on it.

Late in the second quarter, the Ducks were deep in Michigan territory, and Dennis Dixon had everyone fooled on this trick play.

Trailing by a touchdown, Nebraska drove inside the 20 and needed a touchdown to send them to overtime.

With a little luck and a lot of controversy, the Huskers found a way to get it done. Take a look as they get a helping "foot."

With the first half of the 2010 BCS National Championship coming to an end, Texas was trying to run a shovel pass and catch the Crimson Tide off guard.

While the idea may have been good, the execution and result was devastating.

Another Hail Mary that will never be forgotten is the bomb that Kordell Stewart dropped on the Michigan Big House.

Stewart had to launch the pass over 70 yards, and it immediately silenced over 100,000 fans.

In this run, Tommie Frazier showed that he would not be denied on his way to the end zone. Watch him go 75 yards in the Fiesta Bowl against Florida.

The Doug Flutie Hail Mary is a play in sports that will never be forgotten and with good reason.

Flutie is able to evade a defender and then launches a 65-yard bullet to the end zone.

The Play is certainly in the same league as the Flutie Hail Mary. It is a play you that you continue to see on highlight reels around the nation.

With the game seemingly over, watch Cal lateral their way to victory.
