How'd the Dallas Cowboys celebrate Dak Prescott's 28th birthday on Thursday??
A GIANT CAKE TO THE FACE, BABY!!!
Dak's offensive lineman, La'el Collins, appeared to orchestrate the whole thing after 'Boys practice in Oxnard, Calif. ... and it was all funny as hell.
Check out the footage shot by the team ... Collins brought out a cake, and got everyone in attendance to start singing "Happy Birthday" to Dallas' big star.
They eventually coaxed the quarterback to take the cake out of its box ... and as he was admiring his birthday dessert -- Collins, Ezekiel Elliott and a bunch of other Dallas O-lineman shoved it right into his girl!
