S4·E14 Caroline and the Firing Squad

Caroline is appalled to discover that Del (currently obsessed with buying a new Porsche) is paying his partner Charlie to stay at home so that his bizarre ideas won't compromise Del's career. When she persuades Del to let Charlie attend a planning meeting, the plan backfires big time: Charlie is fired. Charlie decides he wants to travel in Europe, and Del does the right thing and gives him the money for his Porsche as severance. Meanwhile, Richard gets Annie a job posing for a cartoonist who starts dating her, but the deal is fishy: it turns out he is only interested in her when she is dressed as the bizarre science fiction heroine of his strip.
