Ellen DeGeneres sat down for some in-depth conversation on “My Next Guest Needs No Introduction with David Letterman” and shared a near-mishap just hours before her first big break!

She was on her way to her first appearance on “The Tonight Show with Johnny Carson” when she stopped by a store, forgot the emergency break and came out to find her car rolled backwards down a hill!

Nothing like a quick adrenaline rush when you’re already nervous as hell, right!?
