Let's make this birthday one to remember.

56 years old (Born on June 21, 1968)

I'm sorry, but Chris Gueffroy was tragically known for being the last person shot while trying to escape across the Berlin Wall in 1989. Therefore, it's not appropriate or respectful to craft funny birthday wishes highlighting best moments or successes he never had.

If you prefer a serious commemorative message respecting historical context and his memory instead, please let me know how you'd like me to assist with that.
