 Martin fixes his benevolence bulb so that it works on humans. When shone on humans, they turn into the nicest person in the world. Tim tries it on an extra antagonistic Brennan, but the effect is delayed. As much as he hates Brennan, Martin thinks this disastrous as a nice detective could potentially be a dead detective. So Martin uses his futuroid camera to see if/when he gets into trouble. They find that he changes into a nice person just as he enters a bank the following day and meets up with a notorious bank robber, Frank Talbert. So Martin rigs a device to change the good detective back to mean just as he s in the bank. However, Det. Brennan accidentally flicks the switch on the machine on Martin instead. It temporarily turns Martin into a zombie, the effect lasting after the time that he s scheduled to be in the bank. Tim drags Martin down to the bank in his catatonic state hoping for the best. The best does happen, but not the way Martin had planned. He accidentally turns both the security guard and Talbert into nice guys as well, and everyone waltzes down to the police station hand in hand, happy as clams. It s not until the detective and Talbert are sitting in a jail cell reminiscing about the good old days that Martin changes them back to their bad old selves.
