While netizens cringe at cheesy promotional videos such as the recent Singapore Tourism Board commercial and SingTel's mRemit advertisement, they are also quick to share others which strike a chord.

The latest case is the World's Toughest Job video which went viral after it was put on YouTube on April 14.

The video, produced by Boston-based advertising agency Mullen for American Greetings as part of the latter's Mother's Day campaign, nabbed more than four million views in the two days following its upload.

The agency posted a job search in print and online for a director of operations for a fictional company called Rehtom.

This job comes with stringent conditions: the worker must stand up almost all the time; work from 135 hours to an unlimited number of hours per week; and have no time to sleep. There would also be no vacations. He or she must also expect his or her workload to increase on occasions like Thanksgiving and Christmas.

Oh, and there would be no pay as well.

Twenty-four unsuspecting people responded to the job posting, out of the 2.7 million impressions it received. They were then interviewed by an actor dressed to look like an executive. Their reactions were captured on webcam - they ranged from disbelief to outrage as the interviewer listed the work conditions.

The four-minute commercial ended with many job applicants in tears when they were told that the work conditions were those faced by mothers all over the world.

The video concluded with the words: "This Mother's Day, you might want to make her a card."

The applicants might not have got the job, but they did gain a newfound respect for mothers.

Here are some other videos from the neighbouring countries that struck a chord:

Petronas - Young Hearts

Malaysian oil company Petronas tugs at heartstrings with its Chinese New Year video called Young Hearts.

It is the latest in a series of videos the firm has done to celebrate festivals such as Chinese New Year, Hari Raya and Deepavali over the past few years.

Young Hearts shows a boy and a girl dressed in new clothes and going to a reunion dinner.

They are late, and their family members are already seated around the dinner table waiting when they arrive.

In the blink of an eye, the two children at the door have now become an elderly couple, but their wide smiles remain.

Part of a campaign done by ad agency Leo Burnett Malaysia, the video encourages viewers to celebrate the festival with the same zest they had when they were children.

Thai Life Insurance - Unsung Hero

Known for its tear-jerking advertisements, Thai Life insurance has done it again this year with Unsung Hero. To date, the three-minute video has received eight million views on YouTube.

The video, produced by Ogilvy & Mather Bangkok, depicts a young man doing his daily rituals. These include watering a dying plant; giving money to a young female beggar; and leaving a bunch of bananas at the door of an elderly neighbour.

He does all these despite the fact that he himself isn't rich and has barely enough to eat when he gets home.

The Thai voice-over says: "He won't be richer. Won't appear on TV. Still anonymous. And not a bit more famous."

Good thing is, his efforts are duly rewarded. He may not be financially richer, but he gains happiness. The plant he waters every day blooms and the beggar eventually goes to school.
