I know the tittle of the post is little confusing.so is the advertisement.
A lady enters the bus. She lifts her hand to hold the grab bar on the top. At the same instant, a man sitting in the bus, closed his mouth. His neighbor closed his nose. The sequence looks as though the men are reacting to the bad smell from the lady. But its an toothpaste advt.
Here is the link. Please view the advt. and post your comments
