Zac Efron says there is nothing worse than having bad breath while filming a kissing scene, and that's exactly what happened to the actor on set of one of his flicks. The lesson Efrom learned was to stay away from stinky foods before locking lips. 
"I chewed more gum that day than typical. No onions!" Efron said. "I had a kissing scene one time and I ate a tuna sandwich and it was the first [scene] I had to do and I got called out on it. It was so embarrassing... You don't do that, don't be that guy!"
