What's the worst play you've ever seen in an NFL or college game?

I'll give you an obscure one:

At a University of Colorado football game a few years back, our punter absolutely SHANKED a kick nearly straight at the moon. It finally came down about 8 yards past the line of scrimmage and took a monster hop backwards. The punter ran up and touched the ball to prevent it from losing more yards. Thus, the punter actually DOWNED HIS OWN PUNT!! I've watched a lot of football and never seen it before or since. Now that is sucktitude.

Has to be the Jim Marshall wrong way run to his own end zone after recovering a fumble followed by throwing the ball in the stands for a safety.

I'd say the Bill Gramatica field goal celebration where he rode a unicycle into a drum of gasoline, causing an explosion that burned 85% of his body.
...the most recent one i can think of is the denver broncos special teams...specifically the punter laying on his back and flailing as devin hester sped by...classic
pros: back in the day the giants had the ball deep in their end of the field, the lead, and about six seconds left on the clock. they were playing the eagles, and instead of taking a knee, they decided to run larry cszonka(?) up the middle. FUMBLE! herm edwards who was a safety at that time for the eagles scooped up the ball and ran into the end zone for a eagles victory.

college: the time that TCU player, (also back in the day), came off the sidelines to tackle a runner headed for the end zone. that is the funniest thing i've ever seen in a game. the runner was going down the sidelines with nothing between him and the goal line. then out of nowhere this player on the sidelines jumps out and tackles him. (ref's awarded the touchdown)
Aaron Brooks "passing" the ball backwards after escaping a sack.
In the super bowl when Ben was down like a yard before the Nzone and they called it a TD.
Running the wrong way in the Rose Bowl is pretty dumb I forget his name though.Jim Marshall also did it with the Vikings
When I was 4 years old, I saw a dog named "Sue," she was a beautiful dog, and I was a beautiful Jew. We lived in a house so big, and every morning we would dig, for the treasure we craved, until Sue went to her grave. I never found that treasure, but now I dance for pleasure.
