Quote from Monica in The One with Chandler's Dad
Ross: I saw the Porsche parked out front. Can I get the keys? I thought I'd take that bad boy for a spin. Rachel: Wait a minute. You let Ross drive the Porsche? Yet when I ask you, you say you're the only one who's allowed to drive it. Monica: Well, he's my brother, and plus he drives so slow he'd never hurt it. Ross: It's a car, Monica, not a rocket ship. Monica: Whatever, Ross. Just replace the bulbs in the brake lights after you're done.
