The mugger was previously described as weighing 180 pounds, yet in this episode, he is reported to weigh 160 pounds.
Assuming the episode is set in 1976, the calendar in the warehouse (reading Wednesday, September 20) does not appear to have been changed since 1972. September 20 fell on a Monday in 1976.
After Bob and Jaime arrest the mugger, they leave the scene without retrieving the woman's purse, even though it's lying on the ground right near them, where it had landed after the mugger threw it at Jaime.
