Let's make this birthday one to remember.

45 years old (Born on September 28, 1979)

Happy Birthday, Bam Margera! From skating fearlessly through the streets to pulling off stunts that made us laugh (and cringe) on Jackass, you've always been a master of chaos and comedy. Who else could turn skateboarding into an extreme sport mixed with slapstick humor? Your legendary pranks have left audiences both amazed and slightly terrified—exactly how you like it.

Here's hoping your birthday is filled with fewer bruises than usual but just as much laughter. Keep shredding life's ramps and rails in true Bam style; after all these years, you're still proving gravity wrong—and making mischief look easy!
