The “Birdman” and “Duplicity” star (if you haven’t seen it, check it out-hilarious!) is celebrating his Birthday this weekend. Other famous people who have B-days this weekend include Roger Waters, Jane Curtain,Jeff Foxworthy,Michael Winslow, and *cough* uhh…I wonder. Celebrate Labor Day and Birdman’s Bday, all while learning something you didn’t know about Mr “Batman” Keaton. Happy Birthday!
