S14E22 Moe Baby Blues
After the blooming of a huge plant in Springfield's botanic gardens causes a stinking fume to spread across town, all the Springfieldians take their cars and drive away from the city. When the traffic is jammed on a bridge, Homer falls asleep. When he accelerates, he crashes into another car and Maggie is sent flying out the open roof window. In the mean time, Moe is about to commit suicide by jumping off the same bridge, which is prevented by Maggie falling into his arms. He then becomes crazily obsessed by the baby.
