Justin Trudeau, the Canadian prime minister. Around the time he beat Senator Patrick Brazeau in a boxing match to raise money for cancer.
The tabloids enjoyed doing this to Tony Blair in his time as Prime Minister.
Then there's that famous picture of Obama...
A September 2009 issue of Newsweek cover featured a Sarah Palin photo that presented her in a less-than-presidential way. Palin and many Newsweek readers were pissed, one who's comment was published in a later issue of the magazine; he asked whether Newsweek would choose to feature a picture of a shirtless Obama"... and they did exactly this, about 20 pages over.
There is a Boston University hockey fan who goes by "Sasquatch" who fires up the crowd by removing his shirt and dancing to "Iron Man". Of course, one doesn't get the name "Sasquatch" if you have a smooth chest and a six-pack...(link, mercifully pic-free).
Matthew McConaughey hardly ever wears a shirt. Exquisitely mocked by Matt Damon on David Letterman: "Ah, Mr. Soderbergh! Today's scene I think would be a good opportunity for me to take my shirt off." If there weren't already three quotes up top, this would be perfect.
DMX would remove his shirt towards the end of his concerts, to the delight of the female fans.
During the 18th and 19th centuries when duelling was popular among gentlemen, some of them noticed that your chances of surviving a fight were better if you didn't get shreds of dirty cloth in your sword cuts or bullet wounds, so they would duel shirtless (and in at least one case, nude).
The men's rowing team at Warwick University are naked in their annual calendar which raises money for Educational Action Challenging Homophobia (EACH).NSFW
On a badminton discussion forum, a badminton player posted that he thinks that being shirtless during his sessions would be better for the environment and he would like to see it become the norm for guys work out bare chest at gyms and health clubs:
I not only play badminton twice or more a week, but squash, tennis and go running as well. It occurred to me after seeing all those notices in hotels about all the towels they unnecessarily wash, that I get through a lot of shirts each week. If you multiply this by the huge number of players around the world, think of how many washing machine loads are players' shirts.
Why do I need to wear a shirt? Usually after 15 minutes of play, my shirt is starting to look as if somebody has spilled water on it, and by the end of a session it is sodden and stuck to me. It interferes with the natural perspiration process and even makes me feel cold when I take a break for a rest.
So will I be making a sensible and green statement by starting my racket sports sessions by removing the shirt I arrive in before starting to play?
Some will say it is unsightly to see shirtless amateur sports people, but this only a conditioned expectation. You think nothing of the various shapes of bodies seen at a swimming pool or on the beach. There are examples of some of our top racket sports people practicing shirtless. particularly tennis players in the sunshine.
So I am willing to go green and shed and shed that unnecessary shirt that only ends up sticking to me, so I can reuse the shirt I arrived in (after toweling down) and save another shirt from the wash.
If we all do the same, then it will become normal practice we will all be greener as a result, saving electricity and detergent pollution.
