What would you do if your child were attacked by an alligator? Would you scream and panic, or would you jump in and fight off the beast? Six-year-old Joey Welch was getting ready for a canoe ride with his dad, Joseph, when he fell off the pier. Right after he splashed into the shallow water, Joseph heard a scream and saw that an alligator had Joey's arm in his jaws!

"I went in it and there was a splash. The alligator just swam into me and clamped my arm," Joey later said. Worse, the alligator started dragging Joey down into the water. How could Joseph free his son without risking tearing off the boy's arm?

The world erupted in cheers last night when Boston police captured America's most wanted man, marathon bombing suspect number two, 19-year-old Dzhokhar A. Tsarnaev. Among the people they were cheering for? Jeff Bauman Jr., the double-amputee in what is now an iconic photo of a man in a yellow cowboy hat rushing a victim in a wheelchair away from the scene of the Boston Marathon bombing.

Bauman, who is also featured in a viral photo of actor Bradley Cooper visiting victims, apparently played a key role in finding the men accused of murdering three and wounding more than a hundred on Marathon Monday. So who is Jeff Bauman? Here's what we know about this new American hero:

When Matthew Bent realized that his son Shiloh's school district wasn't going to take care of a bad bullying situation, he decided to take matters into his own hands.

It's not as ominous as it sounds.

Bent wanted to show the district -- and the world -- that he had his son's back, so he shared a photo on Facebook with this amazing anti-bullying message:

Iconic images of two soldiers in full military fatigues helping victims of the Boston Marathon bombings have been shown all over the media, but it might surprise people to learn that the two Army men weren't stationed at the marathon or on duty. They had, in fact, been participants in the run. Army Sgt. Bernard Madore and Army Sgt. Steve Fiola were taking part in Tough Ruck, a walk in which uniformed soldiers carry 40-pound rucksacks filled with supplies to raise money for charity and honor fallen soldiers. But when disaster hit, they mobilized to save lives.

A supercool dad's Facebook post went viral, in which he describes an interaction he had with a "moron" at a Wal-Mart recently. Apparently, the dad and his little boy, Sam, were standing in the checkout line when Sam asked if he could have the Sofia the First DVD, which was on display nearby. The moron -- Dad's words, not mine (though I'd use that word, too) -- then decided to interject himself into the father-son conversation in order to tell Sam that Sofia the First is a "girl" movie, and it might make him grow up to be "funny". Dad, understandably, didn't like a complete stranger attempting to instill such an idiotic belief in his son, so he put the guy in his place. Here's a screenshot of the Facebook post that describes their interaction:

As parents, we're supposed to be the ones who keep calm in emergencies, right? Don't worry kids, we've got everything under control. But what happens when it's the other way around? Hopefully the kid in question is a lot like 6-year-old Cole Steffens, who was having a bedtime snack with his 17-month-old sister Bailey when she started to choke on a pretzel. "Within seconds, I heard this [makes choking sound]," says dad John. "A pretzel was lodged sideways in her throat."

"I lost it. I was bawling," he admits. Luckily, Cole kept his cool.

My 7-year-old came home excited from school the other day. Apparently during standardized testing, her school is going to allow the kids to chew gum. Great. My kid is being bribed to take yet another test. Way to keep it classy, local elementary school! It's no wonder a mom in Pennsylvania behind a movement to pull your kids out of standardized testing is getting so many followers.

Did you even know you could yank your kid out of these tests?

When a woman was brutally mugged, cops took three weeks trying to find the guy, who was caught on surveillance video perpetrating his sickening crime. No luck. So they put the video on the Internet and asked for help. How long do you think it took to get him now? A day? Half a day? Try an hour. The video, which was quickly picked up by Gawker and some other outlets, showed a young scumbag attacking a 56-year-old woman in the Brooklyn subway, kicking her, and emptying her purse. Three weeks later, cops had not managed to collar the punk. But then they let the Internet do its work.
