On Google, if you search a word, the search engine instantly generates a definition picked up from a website such as Wikipedia, as well as a picture from a, often random, website.
Earlier Google generated controversy for showing the picture of India's current Prime Minister, Nirendra Modi, when someone searched "Top 10 criminals" list on Google Images. After it made it in news and generated the controversy, Google eventually fixed that.
I was searching up different words for getting a better idea of their meaning and different ways of usage, when I happened to search 'Metrosexual'. Apparently as Google generated it's definition from Wikipedia, it picked up a picture for it from a blog, and the picture is an edit of the US President Barack Obama.
According to Google's search, Barack Obama is metrosexual. If this was a more commonly searched thing, it might have become a topic of interest or have caused a few laughs and giggles. But it appears so that it's not a popular topic, so it's not as known. Regardless, it's funny.
