Think Different

Think Different was an advertising slogan made by the advertising agency TBWA\Chiat\day for Apple Computers during the late 1990s. It was used in a famous television commercial and several print advertisements. The slogan was used at the end of several product commercials, until the advent of Apple’s switch ad campaign. Apple currently has no widely used slogan, and their commercials usually end with a silhouetted Apple logo and sometimes a pertinent website address.
Shortly after the death of civil-rights pioneer Rosa Parks on October 24, 2005, the campaign briefly reemerged on Apple's website in reverse type on the famed bus ride photo with the text "Rosa Parks — 1913-2005" in the left corner and "Think Different" in the right. It has been noted that the slogan is grammatically incorrect, and should be "Think Differently" instead. Others have criticized Apple for seemingly trying to associate their brand with historic figures, which may or may not have approved of Apple's products. Supporters of Apple argued that they were paying tribute to the figures in question.

The advertisement is quite wonderful and the lyrics is simply rivetting, it goes like this,

Here's to the crazy ones,
the misfits,
the rebels,
the troublemakers.
The round pegs in the square holes.
The ones who see things differently.

They're not fond of rules
and they have no respect for the status quo.

You can quote them,
disagree with them,
glorify or vilify them.
About the only thing you can't do
is ignore them,
because they change things.
They push the human race forward.

And while some may see them as the crazy ones,
we see genius.

Because the people who are crazy enough to
think they can change the world
are the ones who do.

The original Lyrics is a bit longer. This is a compact version of it.
