Caroline in the City - Season 4 Episode 17
Caroline and the 2000th Strip

Theres to be a big celebrity banquet to celebrate Carolines 2000th strip, but theres a snag: Caroline is completely blocked in terms of fresh, funny ideas. While everyone else waits for her to get ready (Richard in a cheap rental tuxedo which gradually disintegrates), Caroline fantasizes about what life would be like if she retired. When she tearfully refuses to attend the banquet and does laundry instead, Richard gently points out that she has stopped writing about her real life in the strip (her fictional counterpart is ""still dating that veterinarian"") and perhaps it is time to bring her readers up to date -- and Caroline immediately draws a strip about their first date on the side of the washing machine.
