I got it from a ventriloquist comedian known as Jeff Dunham... And one of his puppets is called Walter (pretty much an old guy who has a shitty marriage with his wife). Walter went on about how him and his wife's se>< life was like a new car turning into an old car. This is how it went:
No. Our se>< life it was great. it was... i dunno, like a new car and taking it for a ride WOOHOO! Y'know pushing buttons and twisting knobs. You get it?! Its an analogy dumbazz! And that new car smell WoOoOoOo.
But now it's like getting in that same damn car and you can't get it out of the frickin driveway. Don't even want to warm her up... initially don't even want to take it out of the garage... Sometimes you just gotta choke it... and be careful cuz she does not like reverse...
