Let's make this birthday one to remember.

34 years old (Born on February 03, 1991)

Karim "KO King" Martinez—happy birthday to everyone's favorite Mexican-American southpaw! You came out swinging from day one, making your opponents reconsider their life choices. Charles Sims? TK-whoops. Breuntre Miller? Lights out before lights on. Randolph Cole is probably still wondering what freight train hit him.

You're rising quick in the light welterweight ranks, Karim; we'll need sunglasses just watching you shine. On your special day, may all your wishes land as powerfully and swiftly as those first-round knockouts—but please spare us cake-induced KOs tonight! Keep lighting up rings and smiles alike; happy birthday champ!
