Some people take pride in their funny mugshot photos. They saw an opportunity to take one of the funniest photos of their life and they took it. Others view it as a moment of pause to reflect on all of the life choices that led up to their mugshot. The lucky ones get a pretty decent photo-op out of it.
If you're looking funny mugshots, these probably aren't the mugshots you're looking for. These are weird mugshots and sad mugshots of people realizing they probably just ruined their lives. If you consider this a gallery of amusing mugshots, does that make you a bad person? Yeah, pretty much, but the world needs sadistic people too.
