Bill Gates
If you ever take a tour around the headquarters of Microsoft, there exists a possibility that you will run into the founder of the company himself. This guy might have had a close encounter, but he never did get to meet Bill Gates. It was only after whipping out his phone to check out his photos that he noticed that Bill Gates just photobombed him. This makes for a truly epic story, at any rate.

Jake Gyllenhaal
He might be known for playing serious characters, but we can see that Jake Gyllenhaal is also one goofy guy. When the cute group of girls decided to document their day, they did not know that such a huge celebrity would be included in their photo! How awesome was that? He did not only land a great photobomb in the selfie, but he also did it by pulling off such an insane expression. Never change, Jake.
