In case you didn't know, Tuesday, May 7, was Teacher Appreciation Day. Well, someone should tell that to high school student Jeff Bliss of Duncanville, Texas, who was featured in a video posted to YouTube on Monday. The video, which was shot by a fellow student and has now gone viral, features Bliss ripping into his world history teacher for what he believes are poor teaching practices.

And if you think Bliss regrets his actions, think again. He spoke to ABC's WFAA about why he lashed out at the teacher. He said, "I believe that somebody needed to say this. I want to see a teacher stand up and interact with the students, get involved, discuss, talk, question, and get deep into the subject."

Tammy Kuykendall, chief communications officer for the Duncanville Independent School District, said, "The district is aware of the video, and we are currently addressing the situation."

The video has now been viewed more than 140,000 times. Most of the reactions to Bliss's rant have been positive.

I've seen a lot of men with mustaches, but until today, I had never seen a man who could make his mustache dance. In several videos released by the prank group Whatever, a man named Clydesdale shows off his creative trick of making his mustache boogie.

The pranksters said they were on their way back from filming one of their pranks when they met Clydesdale for the first time.

After the initial video went viral, with more than 1.8 million views to date, the guys of Whatever wanted to show their appreciation for the man who got them to over 100,000 subscribers for their YouTube channel. So they started a crowdsourcing campaign on Indiegogo to raise $3,000 to give to Clydesdale. For one month, the group posted follow-up videos featuring the rising star and even threw in $300 of their own money. There was only one thing left to do: Give the money to Clydesdale in person. In addition to the cash, the group gave him a gift certificate and some clothing -- including a T-shirt that reads, "My

A new invention may help ease the fears of people who live in or work in high-rise buildings. It's called the SOS Parachute, and its inventor, Morris Shahbazi of Panama, describes the product as a high-evacuation system that can be used in the event of a fire or a disaster.

Shahbazi says he has tested his SOS Parachute 13 times himself, and each of those 13 times, he was successful. So what makes his parachute different from a conventional chute? Shahbazi said, "My chute opens faster than a conventional parachute, and as a result it needs only 100 feet of drop to be fully operational." In case you're wondering, that's about 10 stories high in most buildings.

Shahbazi said that he got the idea for the life-saving apparatus after the World Trade Center attacks on September 11, 2001. So far, people have been writing positive comments about the concept of the parachute, with many saying they're anxious to get their hands on one and test it out. (Um – our advice?
