Curb Your Enthusiasm S01 E07 AAMCO

"Deep inside you know you're him."

Jeff gets a new car, and when Larry takes it for a spin, a commercial comes on the radio for AAMCO, with a noise sounding much like a car horn from behind. Upon hearing this, Larry curses the man behind him, prompting the man to rear-end Jeff's brand new car. Also, Larry and Cheryl hold a dinner party.
