He's Vince Vaughn and you're definitely not

Look kids, a fallen star:

IS former big-screen everyman Chevy Chase trying to start a feud with his modern-day counterpart, Vince Vaughn? "Recently, I saw a commercial with, is it Nicole Kidman? No, no - Jennifer What's Her Name? from 'Friends,' " Chase tells Details. "And some guy. I had never seen him. I don't know who the [bleep] he is. He looks like some refrigerator repairman." (Chase was referring to a commercial for the Jennifer Aniston/Vaughn comedy, "The Break-Up.")

It's been a long time since Caddyshack and Vacation (and yes, we're sparing you from the part where he jokes about his 17-year-old daughter being a whore)...
