One of the fascinations of the Internet is that sites like YouTube have the ability to turn ordinary people into heroes overnight — or in some cases, within a few hours.

Joey Prusak, a Dairy Queen manager in Minnesota, became an Internet sensation after he responded to a situation by doing, well, what anyone should have done. Working the counter Sept. 10, Prusak saw a blind man drop a $20 bill. When a woman stooped to pick it up, he assumed she would return it to him. When she pocketed it instead, Prusak politely asked her give it back. When she refused, the 19-year-old refused to serve her. He then took $20 out of his own pocket and gave it to the blind man.

Customers who witnessed the exchange couldn’t keep it to themselves. An email written to Dairy Queen management found its way to Facebook, where it went viral. Prusak’s good deed caught the attention of the likes of Glenn Beck and billionaire Warren Buffett, whose company owns Dairy Queen.

When interviewed, Prusak said he “was just doing what I thought was right.”

“Ninety-nine out of 100 people would’ve done the same thing,” he said.

The Internet sensation created by his small act of kindness seems to suggest otherwise. Are good deeds so rare these days that any act of kindness or honesty, no matter how small, results in shock and awe? Do we overlook injustices like the one Prusak encountered so often that we feel the need to rejoice when someone acts in an ethical — or dare we say Christian — manner?

Prusak’s kind act absolutely is one that deserves to be commended. But wouldn’t it be great if we lived in a society in which doing the right thing was the rule rather than the exception?
