5. CHARLES BARKLEY AS HIMSELF IN LOOK WHO'S TALKING NOW (1993)
Look Who’s Talking was a cute, clever little comedy that detailed what life is like seen through the eyes of a newborn. Then the sequel came, and it kinda was the same shit—but it still wasn’t super terrible. Then another sequel came, this one through the perspective of dogs, and that's when things went completely off the cliff.
We could go on for pages and pages about all the things that are wrong with this flick (a list for another day!) but we’re going to focus on the Charles Barkley cameo here. It's tuuuurrible, even by corny athlete standards. It's a dream sequence of him getting beat in a game of basketball by the little girl, Julie. It's actually kind of surprising how bad his acting is in this, this part should have come natural to him considering Michael Jordan torched his ass the exact same way during the '93 NBA finals.
